Description

Technical Field

[0001] This utility model relates to the technical field of clothing care devices, and specifically to a rotating shaft assembly of a clothing care device. Background Technology

[0002] With the improvement of people's living standards, washing machines have become one of the main household appliances in daily life. The inner drum of the washing machine is rotatably connected to the cavity of the outer drum. A rotating shaft is fixedly connected to the bottom of the inner drum, and a bearing seat is correspondingly provided on the outer drum. The bearing seat has a shaft hole that passes through the inside and outside of the outer drum, and the rotating shaft is rotatably connected to the bearing seat. Therefore, a sealing structure is needed between the rotating shaft and the outer drum or bearing seat to prevent water leakage while allowing the rotating shaft to rotate.

[0003] Traditional sealing structures typically consist of an elastic sealing ring that comes into close contact with a rotating shaft or bushing to form a sealing interface, relying on the elastic deformation of the material to compensate for minor axial or radial deviations. However, this type of traditional sealing structure has significant limitations: when the washing machine rotates at high speed for extended periods, the sealing ring, which acts directly on the rotating shaft, is prone to wear and aging, leading to malfunctions such as seal damage and water leakage from the outer drum.

[0004] There is an existing washer-extractor spindle sealing device with publication number CN104864096B, which forms a rotary seal structure through component A ring and component B ring. Although it can solve the problems of easy damage and short service life of traditional sealing structures, the structure is complex and the structure of maintaining the contact of component A ring and component B ring by spring pressure will still face durability problems after long-term use. Moreover, the existing rotary seal device only serves the single goal of preventing leakage and has a single function, which cannot meet the diverse needs of modern clothing care.

[0005] Therefore, it is necessary to provide a new approach to solve the aforementioned technical problems. Utility Model Content

[0215] Terms involving attachment, connection, etc. (e.g., “connection” and “attachment”) refer to the relationship in which these structures are directly or indirectly fixed or attached to each other through an intermediate structure, as well as movable or rigid attachments or relationships, unless otherwise explicitly stated.

[0216] Example 1

[0217] This utility model embodiment provides a rotating shaft assembly for a garment care device 1, which forms a rotational support for the inner cylinder 120 of the garment care device 1; combined with Figures 1-7b As shown, it includes:

[0218] Rotation axis 131;

[0219] The sealing ring assembly 140 includes a first annular member 141 and a second annular member 142 whose end faces are tightly fitted together; wherein, the first annular member 141 is fixed to the rotating shaft 130, and the second annular member 142 is installed on the outer cylinder 110 of the garment care device 1, and the first annular member 141 can abut against the second annular member 142 when rotating with the rotating shaft 130 to form a dynamic seal at the end of the rotating shaft 131;

[0220] A fluid passage 143 is formed between the first annular member 141 and the second annular member 142 within at least one continuously closed sealing ring assembly 140 to connect the gas and / or liquid environments inside and outside the cylinder while the end of the rotating shaft 131 is sealed.

[0221] The continuously closed fluid passage 143 can be understood as maintaining continuity whether the first annular member 141 rotates with the rotating shaft 131 or the first annular member 141 and the second annular member 142 remain stationary, and effectively isolating the internal fluid from the outside. Its function is to ensure that gas and / or liquid can be continuously and stably delivered to the inside or outside of the cylinder regardless of whether the inner cylinder 120 rotates, while preventing fluid leakage, reducing pressure loss, and ensuring the functionality and structural reliability of the garment care device 1.

[0222] For example, water can be introduced into the inner drum 120 during rotation via fluid passage 143; or washing water can be drawn into the drum via fluid passage 143 to perform washing circulation; or detergent can be added or specific liquid additives (such as fabric softener or disinfectant) can be injected into the rotating inner drum 120 during washing via fluid passage 143; or hot air or dehumidified dry and cold air can be introduced between the rotating inner drum 120 and the outer drum 110 via fluid passage 143 to perform drying function; or steam can be injected into the rotating drum via fluid passage 143 to perform steam care function, etc.

[0223] This embodiment not only efficiently and reliably completes the rotational dynamic sealing function, but also integrates a continuous closed fluid passage 143 between the mutually fitting first annular member 141 and second annular member 142, thus integrating both rotational sealing and fluid delivery functions during rotation. This enhances the functional diversity of the garment care device 1 and optimizes the user experience. The fluid passage 143 is embedded inside the sealing ring assembly 140, avoiding excessive additional space occupation and minimizing space usage. The assembly structure, which fixes the first annular member 141 to the rotating shaft and the second annular member 142 to the outer cylinder 110, provides a stable sealing pressure between the first annular member 141 and the second annular member 142 and a stable pressure boundary for the fluid passage 143. On the other hand, it effectively simplifies the assembly method of the sealing ring assembly 140, making the axial structure more compact and eliminating the need for the spring-pressurized structure found in existing technologies.

[0224] In some embodiments, the end face of the first annular member 141 is provided with at least one first flow channel groove 1411, and the end face of the second annular member 142 is provided with at least one second flow channel groove 1421.

[0225] Each of the first flow channel grooves 1411 and the corresponding second flow channel grooves 1421 defines an independent fluid passage 143.

[0226] For example, in this embodiment, the end face of the first annular member 141 is provided with a first flow channel groove 1411, and the end face of the second annular member 142 is provided with a second flow channel groove 1421. The shapes of the first flow channel groove 1411 and the second flow channel groove 1421 are adapted to each other. When the first annular member 141 and the second annular member 142 are assembled, the first flow channel groove 1411 and the second flow channel groove 1421 together define a fluid passage 143. When the first annular member 141 rotates with the rotating shaft 130, the fluid passage 143 can always remain in a continuously closed state.

[0227] It should be understood that the end face of the first annular member 141 may also be provided with two, three or more first flow channel grooves 1411, and the end face of the second annular member 142 may be provided with two, three or more second flow channel grooves 1421, so that two, three or more fluid passages 143 can be formed between the first annular member 141 and the second annular member 142.

[0228] like Figure 4a The second annular member 142 is provided with a second flow channel groove 1421a and a second flow channel groove 1421b. Correspondingly, the first annular member 141 is also provided with two first flow channel grooves 1411 (not shown in the figure). Thus, two fluid passages 143 are formed between the second annular member 142 and the first annular member 141. Figure 4b The first fluid passage 143a and the second fluid passage 143b are shown.

[0229] In some alternative embodiments, the first flow channel 1411 and the second flow channel 1421 are both annular, rectangular, or waist-shaped structures. In some preferred embodiments, the first flow channel 1411 and the second flow channel 1421 are both annular structures; specifically, the first flow channel 1411 and the second flow channel 1421 form a continuous annular groove structure, and the first flow channel 1411 and the second flow channel 1421 can be combined to form a continuous, closed annular tubular channel or cavity, i.e., the fluid passage 143. The center of the annular groove structure coincides with the rotation center of the rotating shaft 130, meaning that the fluid passage 143 is always symmetrical with respect to the rotating shaft 130. When the first annular member 141 rotates with the rotating shaft 130, it can effectively reduce the dynamic balance effect of the fluid passage 143 on the high-speed rotating shaft 130, improving the smoothness of the rotating shaft 130's operation. Furthermore, due to the symmetry of the fluid passage 143, the contact pressure and fluid pressure distribution on the sealing end face of the sealing ring assembly 140 are more uniform, which helps to extend the service life of the sealing ring assembly 140. The structure is simple and easy to process and manufacture.

[0230] Furthermore, the multiple first flow channel grooves 1411 and second flow channel grooves 1421 are distributed in a concentric annular shape; each group (i.e., one first flow channel groove 1411 and one corresponding second flow channel groove 1421) forms an independent fluid passage 143. Fluid passages 143 of different radii are isolated from each other and independent, and can be used to transport different fluids at the same time; annular flow channel grooves of different sizes can be designed as needed to adapt to fluids with different flow rates or different viscosities.

[0231] In some embodiments, the outer peripheral surface of the first annular member 141 is provided with at least one connecting hole 1412. One end of the connecting hole 1412 is connected to the first flow channel groove 1411, and the other end is connected to the inside of the outer cylinder 110. Specifically, the connecting hole 1412 extends radially from the outer peripheral surface of the first annular member 141 to the first flow channel groove 1411, and the fluid passage 143 is connected to the internal environment of the outer cylinder 110 through the connecting hole 1412.

[0232] Furthermore, a plurality of connecting holes 1412 are evenly distributed on the outer circumferential surface of the first annular member 141. For example, taking the conveying of fluid into the outer cylinder 110 as an example, when the fluid enters the fluid passage 143, it will be evenly conveyed to the inner cylinder 120 from multiple directions around the circumference of the rotating first annular member 141. Moreover, since the connecting holes 1412 rotate with the first annular member 141, the fluid can be output in a jet-like manner during the rotation, further enhancing the uniformity of distribution.

[0233] In some embodiments, an interface 1422 is formed on the outer peripheral surface of the second annular member 142. One end of the interface 1422 is connected to the second flow channel groove 1421, and the other end is connected to an external gas-liquid pipeline. By setting the gas-liquid supply or recovery pipeline on the stationary second annular member 142, there is no need to arrange dynamic connections on the rotating first annular member 141 or the rotating shaft 130, thus avoiding the problems of complex and easily damaged dynamic rotary joints or hose entanglement. Moreover, the connection method is simple and quick, and is convenient for manufacturing, assembly and maintenance.

[0234] Furthermore, the outer peripheral surface of the second annular member 142 is provided with a plurality of interfaces 1422; specifically, when a plurality of fluid passages 143 are formed in the sealing ring assembly 140, each fluid passage 143 corresponds to at least one interface 1422.

[0235] Furthermore, valves, pumps, or other structures that enable precise flow path control can be independently installed at the interface 1422, or between the interface 1422 and the external gas-liquid pipeline, or on the gas-liquid pipeline.

[0236] In some embodiments, the end faces of the first annular member 141 and the second annular member 142 are provided with ceramic layers; they have excellent sealing performance, and their high hardness and wear resistance can ensure that they maintain excellent sealing effect and sealing accuracy even after long-term operation, thus extending the service life of the sealing ring assembly 140.

[0237] In some other embodiments, the sealing ring assembly 140 is a ceramic sealing ring assembly 140; specifically, the sealing ring assembly 140 is made entirely of ceramic material, which further maintains long-term sealing performance and can better adapt to the complex chemical environment inside the garment care device 1, avoiding seal damage caused by corrosion or the generation of corrosion products.

[0238] In some embodiments, the first annular component 141 is integrally formed with the rotating shaft; this improves the reliability of the sealing performance, provides high structural strength and excellent stability, facilitates a compact structure, and reduces assembly complexity; and the integral forming can effectively ensure that the axis of the rotating first annular component 141 is coaxial with the rotating shaft 130, eliminates axial or radial offset caused by separate assembly, and ensures balance during high-speed rotation.

[0239] In some embodiments, a first sealing structure 1423 is provided between the second annular member 142 and the outer cylinder 110 to prevent washing water inside the cylinder from overflowing from the assembly point of the second annular member 142 and the outer cylinder 110, causing water leakage in the cylinder or even damage to the circuit; furthermore, the first sealing structure 1423 is a sealing ring, which has a simple structure, is easy to install, can provide a static seal between the second annular member 142 and the outer cylinder 110, and has good reliability and adaptability.

[0240] In some embodiments, combined with Figures 5-7b As shown, it also includes a gas-liquid conveying component 150, which is installed with the first annular component 141; and the gas-liquid conveying component 150 is connected to the fluid passage 143 and the inner cylinder 120 respectively, to form a gas and / or liquid guiding structure. Specifically, the gas-liquid conveying component 150 and the first annular component 141 rotate synchronously with the rotating shaft 130. Gas and / or liquid enter the gas-liquid conveying component 150 through the connecting hole 1412 of the first annular component 141. The gas-liquid conveying component 150 redirects the fluid from the fluid passage 143 to be introduced into the inner cylinder 120, that is, the gas-liquid conveying component 150 is used to achieve precise gas and / or liquid guiding.

[0241] The shape of the gas-liquid conveying component 150 is adapted to the bottom of the inner cylinder 120. In this embodiment, the gas-liquid conveying component 150 is disc-shaped; different shapes of gas-liquid conveying components 150 can be designed as needed.

[0242] Furthermore, at least one chamber 151 is formed inside the gas-liquid conveying component 150; a fluid passage 143 communicates with at least one of the chambers 151. In this embodiment, a fluid passage 143 is formed inside the sealing ring assembly 140, and a chamber 151 is formed inside the gas-liquid conveying component 150. The fluid passage 143 and the chamber 151 are connected through the connecting hole 1412. When multiple fluid passages 143 are formed inside the sealing ring assembly 140, multiple chambers 151 are formed inside the gas-liquid conveying component 150. Each fluid passage 143 communicates with at least one chamber 151, enabling the on-demand distribution or mixing of water, air, or detergent. In addition, the chamber 151 can also provide buffering for pressure fluctuations during fluid transport.

[0243] In some embodiments, the gas-liquid conveying component 150 is provided with at least one set of through holes 152 on the surface facing the bottom of the inner cylinder 120; each of the chambers 151 is connected to at least one set of through holes 152; this embodiment can further achieve precise positioning and conveying of fluid through the through holes 152, and increase the coverage area of ​​the gas-liquid conveying component 150, reduce blind spots, and make the fluid form a flow path along the axial direction of the cylinder.

[0244] Furthermore, the number of through holes 152 in each group is 3-12. In this embodiment, the number of through holes 152 in each group is 6.

[0245] In some embodiments, the arrangement of the through holes 152 matches the arrangement of the drain holes 121 at the bottom of the inner cylinder 120 to ensure smooth fluid flow.

[0246] Furthermore, the through hole 152 protrudes from the surface of the gas-liquid conveying component 150 to cooperate with the drain hole 121; specifically, when the gas-liquid conveying component 150 is installed, the through hole 152 can extend into the drain hole 121 to connect with the internal environment of the inner cylinder 120, so that fluid can enter the inner cylinder 120 or exit from the inner cylinder 120 more quickly and smoothly.

[0247] In some embodiments, a switch structure is provided at the through hole 152 to open or block the flow path of gas and / or liquid, thereby achieving dynamic and precise control of the flow path of gas and / or liquid; the switch structure includes a damper, a pump body, or a valve body, etc.

[0248] In some embodiments, the gas-liquid conveying component 150 is detachably installed with the first annular component 141; on the one hand, it facilitates disassembly, maintenance or replacement when blocked by scale or additive crystals; on the other hand, it facilitates the replacement of replacement parts with different structures to expand the function of the gas-liquid conveying component 150.

[0249] Furthermore, a second sealing structure 153 is provided between the gas-liquid conveying component 150 and the first annular component 141 to prevent fluid from overflowing from the assembly point of the gas-liquid conveying component 150 and the first annular component 141; furthermore, the first sealing structure 1423 is a sealing ring, which has a simple structure, is easy to install, can provide a static seal between the gas-liquid conveying component 150 and the first annular component 141, and has good reliability and adaptability.

[0250] Furthermore, the outer peripheral surface of the first annular member 141 protrudes radially to form an annular first sealing groove 1413 and a second sealing groove 1414, and a flow groove 1415 is formed between the first sealing groove 1413 and the second sealing groove 1414; wherein, the first sealing groove 1413 and the second sealing groove 1414 are used to arrange sealing rings, the connecting hole 1412 of the first annular member 141 is located in the flow groove 1415, and the flow groove 1415 communicates with the chamber 151; when the gas-liquid conveying member 150 is installed with the first annular member 141, the sealing rings on both sides are squeezed to form a seal, and the fluid in the fluid passage 143 enters the chamber 151 through the connecting hole 1412 and the flow groove 1415.

[0251] Example 2

[0252] To improve the efficiency of washing machine laundry or to perform specific functions, it is often necessary to introduce washing water during the rotation of the inner drum, such as performing water intake or circulating spraying operations. Currently, the mainstream technical solution for achieving water intake or spraying functions in washing machines mainly relies on setting water inlets or spray nozzles at specific positions on the outer drum for fixed-position spraying. However, the spraying direction of fixed-position water inlets or spray nozzles is preset and cannot move with the clothes, which can easily create spray blind spots. It is difficult to ensure that the sprayed water flow can effectively cover all areas of the inner drum, and the spraying uniformity is poor, which reduces the user experience.

[0253] Therefore, this embodiment of the invention also provides a cylindrical body for a garment care device 1, combined with... Figures 8-12 As shown, it includes:

[0254] Inner cylinder 220, the inner wall of which is provided with lifting ribs 221;

[0255] outer cylinder 210;

[0256] Tripod 230 is fixedly connected to the bottom of the inner cylinder 220 to transmit rotational driving force to the inner cylinder 220; and the end of the tripod 230 extends axially along the inner cylinder 220 and passes through the outer cylinder 210 to form a rotation shaft 231.

[0257] The sealing ring assembly 240 includes a first annular member 241 and a second annular member 242 whose end faces are tightly fitted together. The first annular member 241 is fixed to the rotating shaft 231, and the second annular member 242 is installed on the outer cylinder 210. When the first annular member 241 rotates with the rotating shaft 231, it can abut against the second annular member 242 to form a dynamic seal at the end of the rotating shaft 231. At least one continuously closed fluid passage 243 is formed between the first annular member 241 and the second annular member 242 within the sealing ring assembly 240 to connect the liquid environment inside and outside the cylinder when the end of the rotating shaft 231 is sealed; that is, it can deliver washing water into the cylinder during the rotation of the inner cylinder 220.

[0258] A water channel 260 is installed with the second annular member 242 and communicates with at least one of the fluid passages 243 to provide washing water to the fluid passages 243;

[0259] A gas-liquid conveying component 250 is installed with the first annular component 241; and the gas-liquid conveying component 250 is connected to the fluid passage 243 and the inner cylinder 220 respectively to form a washing water guiding structure.

[0260] The gas-liquid conveying component 250 includes at least one conveying pipe 251, which extends into the interior of the lifting rib 221 to spray water onto the clothes inside the drum through the lifting rib 221.

[0261] This embodiment not only efficiently and reliably completes the rotational dynamic sealing function, but also integrates a continuous closed fluid passage 243 between the mutually fitting first annular member 241 and second annular member 242, thus integrating both rotational sealing and fluid delivery functions in the rotational state. This enhances the functional diversity of the garment care device 1 and optimizes the user experience. The fluid passage 243 is embedded inside the sealing ring assembly 240, avoiding excessive additional space occupation and minimizing space occupancy.

[0262] The assembly structure that fixes the first annular component 241 to the rotating shaft and the second annular component 242 to the outer cylinder 210 provides a stable sealing pressure between the first annular component 241 and the second annular component 242 and a stable pressure boundary for the fluid passage 243. On the other hand, it effectively simplifies the assembly method of the sealing ring assembly 240, making the axial structure more compact.

[0263] The washing water from the fluid passage 243 is redirected into the lifting ribs 221 of the inner drum 220 via the gas-liquid conveyor 250. When the washing water is sprayed out from the lifting ribs 221, it can impact the surface of the clothes with a certain pressure and angle, enhancing the dissolution of stains. Furthermore, when the lifting ribs 221 rotate with the inner drum 220, they will lift the clothes to a high place and then throw them down. At the same time, the sprayed washing water can form a combined spraying and tumbling effect during the fall of the clothes, so that each piece of clothing can fully contact the washing water, effectively improving the cleaning effect.

[0264] In some embodiments, the gas-liquid conveying member 250 includes a conveying pipe 251 that extends into the interior of a lifting rib 221.

[0265] In some preferred embodiments, the number of conveying pipes 251 matches the number of lifting ribs 221, and each conveying pipe 251 extends into a corresponding lifting rib 221. Specifically, each lifting rib 221 is connected to a conveying pipe 251 to create a multi-directional water outlet / spray effect inside the drum, expanding the water flow coverage area. That is, each lifting rib 221 can simultaneously rinse clothes in different directions as it rotates with the inner drum 220, reducing blind spots and improving cleaning efficiency. Furthermore, the multi-directional water flow impact formed by the lifting ribs 221 inside the drum can reduce clothes tangling, keeping clothes in a relaxed state during washing and reducing the risk of deformation.

[0266] Furthermore, the lifting rib 221 has an installation port 2212 on its side near the bottom of the inner cylinder 220, and the conveying pipe 251 passes through the bottom of the inner cylinder 220 and the installation port 2212, and connects to the inside of the lifting rib 221.

[0267] In some embodiments, the lifting rib 221 has a plurality of first through holes 2211 for allowing washing water output from the conveying pipe 251 to pass through. Specifically, after the washing water enters the interior of the lifting rib 221 through the conveying pipe 251, it is sprayed into the inner drum 220 through the first through holes 2211. By providing a plurality of first through holes 2211, the washing water can be distributed in a spray pattern, which can decompose the water flow into a fine water curtain, which is beneficial for penetrating clothing fibers and cleaning inner layer stains.

[0268] In some embodiments, the first through hole 2211 is distributed at the bottom of the lifting rib 221 so that water is sprayed radially along the inner drum 220, that is, the water can act vertically on the clothes. Specifically, when the inner drum 220 rotates, the centrifugal force will press the clothes against the drum wall or cover the lifting rib 221, and the water sprayed radially along the inner drum 220 can directly penetrate the clothes. Unlike the traditional method of only setting the top spray, which is easily blocked by the surface of the clothes, the method in this embodiment can effectively improve the washing water penetration rate and cleaning ability.

[0269] In some embodiments, a plurality of first through holes 2211 are distributed along the length direction of the lifting rib 221; specifically, the first through holes 2211 are distributed along the axial direction of the inner cylinder 220. Further, the distribution range of the plurality of first through holes 2211 covers both ends of the lifting rib 221; specifically, the distribution range extends from one end of the lifting rib 221 to the other end, to cover the entire bottom of the lifting rib 221; this effectively reduces blind spots in the washing process and increases the spray coverage area.

[0270] In some embodiments, the first through holes 2211 include at least two different apertures, which can form different water spray volumes; specifically, the water flow in the large aperture first through hole 2211 is sprayed out in a columnar shape to increase the rinsing force; the water flow in the small aperture first through hole 2211 is sprayed out in a mist shape to form a high-speed fine stream to penetrate the fibers; the first through holes 2211 with multiple apertures can improve cleaning efficiency and better adapt to various washing scenarios.

[0271] Furthermore, the aperture is 0.5-5mm; for example, the small aperture is set to 0.5-2mm; and the large aperture is set to 3-5mm.

[0272] In some embodiments, the conveying pipe 251 and the gas-liquid conveying component 250 are integrally formed; on the one hand, this eliminates the need for complex assembly structures and simplifies the overall structure; on the other hand, the integral forming process can improve structural strength and provide better sealing, ensuring the precise directional delivery of washing water.

[0273] Furthermore, the conveying pipe 251 includes an extension 2511 and a connecting portion 2512; wherein,

[0274] The extension 2511 extends from the outer side of the gas-liquid conveying component 250 to the edge of the inner cylinder 220;

[0275] One end of the connecting part 2512 is connected to the extension part 2511, and the other end passes through the tripod 230, the bottom of the inner cylinder 220, and is installed with the lifting rib 221.

[0276] Specifically, the tripod 230 forms a positioning structure for limiting the position of the gas-liquid conveying component 250; wherein, the tripod 230 is provided with a recess 232, and the gas-liquid conveying component 250 is located in the recess 232; in this embodiment, three conveying pipes 251 are provided, and the extension 2511 of each conveying pipe 251 extends along the support arm 233 of the tripod 230 to a position close to the end of the support arm 233, and the connecting part 2512 passes through the hollow structure 2331 of the support arm 233 and the bottom of the inner cylinder 220, and then connects to the lifting rib 221.

[0277] In some embodiments, the water channel 260 connects to the inlet water channel and / or the circulating water channel. In some embodiments, the water channel 260 is connected to the inlet water channel, and the lifting ribs 221 spray water onto the clothes in the inner drum 220, accelerating the dissolution of detergent and its penetration into the gaps in the clothing fibers, thus mechanically scouring stubborn stains such as oil stains and sweat stains and improving cleaning efficiency. In still other embodiments, the water channel 260 is connected to the circulating water channel. For example, during the rinsing stage, the sprayed water can directly rinse away residual detergent on the surface of the clothes, and combined with the agitation effect of the lifting ribs 221, it increases the rinsing effect and further saves water and energy.

[0278] This utility model embodiment also provides a garment care device 1, including a cylindrical body as described in the above embodiment. This embodiment not only efficiently and reliably completes the rotary dynamic sealing function, but also integrates a continuous closed fluid passage 243 between the mutually fitting first annular member 241 and second annular member 242, thus integrating both rotary sealing and fluid delivery functions during rotation, thereby enhancing the functional diversity of the garment care device 1 and optimizing the user experience.

[0279] Example 3

[0280] Currently, the mainstream technology for water intake in washing machines involves setting up a water inlet at a specific location on the outer drum to execute the water intake program at a fixed position. However, the water flow direction of the fixed-position water inlet is preset and cannot move with the clothes. The water flow may only contact the clothes on the upper part of the inner drum, which can easily lead to the accumulation of upper clothes while the lower clothes are not adequately wetted. Furthermore, if the water flow is blocked by the inner drum wall, it may result in insufficient detergent dissolution or uneven soaking of clothes, affecting the washing effect and reducing the user experience.

[0281] Therefore, this embodiment of the invention also provides a cylindrical body for a garment care device 1, combined with... Figures 1-14 As shown, it includes:

[0282] Inner cylinder 320; outer cylinder 310;

[0283] Tripod 330 is fixedly connected to the bottom of the inner cylinder 320 to transmit rotational driving force to the inner cylinder 320; and the end of the tripod 330 extends axially along the inner cylinder 320 and passes through the outer cylinder 310 to form a rotation shaft 331.

[0284] The sealing ring assembly 340 includes a first annular member 341 and a second annular member 342 whose end faces are tightly fitted together. The first annular member 341 is fixed to the rotating shaft 331, and the second annular member 342 is installed on the outer cylinder 310. When the first annular member 341 rotates with the rotating shaft 331, it can abut against the second annular member 342 to form a dynamic seal at the end of the rotating shaft 331. At least one continuously closed fluid passage 343 is formed between the first annular member 341 and the second annular member 342 within the sealing ring assembly 340 to connect the liquid environment inside and outside the cylinder when the end of the rotating shaft 331 is sealed, that is, to deliver water into the cylinder during the rotation of the inner cylinder 320.

[0285] The water inlet passage 360 ​​is installed with the second annular member 342 and communicates with at least one of the fluid passages 343 to provide water inlet flow to the fluid passage 343;

[0286] The gas-liquid conveying component 350 is installed with the first annular component 341; and the gas-liquid conveying component 350 is connected to the fluid passage 343 and the inner cylinder 320 respectively to guide the inlet water flow in a directional manner, forming an axial water inlet structure of the garment care device 1.

[0287] This embodiment not only efficiently and reliably completes the rotational dynamic sealing function, but also integrates a continuous closed fluid passage 343 between the mutually fitting first annular member 341 and second annular member 342, thus integrating both rotational sealing and fluid delivery functions in the rotational state. This enhances the functional diversity of the garment care device 1 and optimizes the user experience. The fluid passage 343 is embedded inside the sealing ring assembly 340, avoiding excessive additional space occupation and minimizing space occupancy.

[0288] The assembly structure, which fixes the first annular component 341 to the rotating shaft and the second annular component 342 to the outer cylinder 310, provides a stable sealing pressure between the first annular component 341 and the second annular component 342 and a stable pressure boundary for the fluid passage 343. On the other hand, it effectively simplifies the assembly method of the sealing ring assembly 340, making the axial structure more compact.

[0289] The water flow from the fluid passage 343 is redirected by the gas-liquid conveyor 350 and axially transported into the inner drum 320. This breaks through the water flow blind spots of traditional water inlet methods, allowing the axial water flow to more evenly cover all areas of the inner drum 320 and penetrate more easily into the interior of the clothes. Furthermore, the axial water flow direction is aligned with the rotation direction of the inner drum 320, which accelerates the dissolution and diffusion of detergent in the water, allowing clothes to be soaked more quickly and stains to be broken down more easily. On the other hand, the axial water flow has a gentler impact on the clothes. The axial water flow is injected directly along the axis of the inner drum 320, resulting in a more concentrated water flow impact that is consistent with the axis of the inner drum 320, preventing violent lateral pulling on the clothes. The uniform axial water flow also keeps the clothes relatively loose in the water, reducing friction.

[0290] This embodiment optimizes the water inlet flow path, improves the uniformity of water flow distribution, reduces damage to clothes, and meets users' needs for efficient and gentle washing.

[0291] In some embodiments, the water inlet path 360 includes a water inlet pipe embedded in the bottom of the outer cylinder 310. Integrating the water inlet pipe into the wall thickness of the bottom of the outer cylinder 310 significantly saves axial and radial space, maximizing space utilization and achieving a compact structure. Furthermore, the water inlet pipe being hidden inside the bottom of the outer cylinder 310 completely avoids the risk of interference between exposed pipes and the rotating shaft 331, improving operational reliability.

[0292] In some other embodiments, the water inlet channel 360 includes a water inlet groove 361 formed at the bottom of the outer cylinder 310 and a water inlet cover 362 covering the water inlet groove 361, simplifying the manufacturing process and reducing manufacturing costs. Specifically, the water inlet groove 361 is integrally formed with the outer cylinder 310, possessing good structural strength and contributing to structural stability. Furthermore, the water inlet cover 362 is detachably connected to the water inlet groove 361 by screws or snap-fit ​​structures, facilitating maintenance or cleaning. For example, it can be opened to clean the sediment in the water inlet groove 361, preventing blockages.

[0293] In some preferred embodiments, the water inlet passage 360 ​​extends from the second annular member 342 to the bottom edge of the outer cylinder 310, and forms a water inlet 311 at the bottom of the outer cylinder 310. The water inlet 311 is used to assemble with the water inlet device 370 of the garment care device 1. Specifically, the water inlet 311 protrudes axially from the bottom surface of the outer cylinder 310, and is used to communicate with an external water inlet pipe, which is connected to a water inlet valve. The incoming water is transported from the water inlet valve through the external water inlet pipe to the water inlet 311, and then enters the water inlet passage 360, and is then transported from the water inlet passage 360 ​​to the fluid passage 343.

[0294] In some embodiments, the gas-liquid conveying member 350 has at least one chamber 352 formed inside; a fluid passage 343 communicates with at least one chamber 352; the chamber 352 is used to form a transition space for the incoming water flow; after the incoming water flow enters the chamber 352 of the gas-liquid conveying member 350 through the fluid passage 343, the space inside the chamber 352 can be used to buffer the pressure fluctuation of the incoming water flow, making the output water flow pressure more stable; and the chamber 352 can also be used to temporarily store the incoming water flow, adjust the flow difference between the input and output, and avoid excessive instantaneous flow.

[0295] Furthermore, the fluid passage 343 is also connected to the detergent dispensing device of the garment care device 1, and the detergent enters the gas-liquid conveying component 350 through the fluid passage 343;

[0296] The gas-liquid conveying component 350 is configured to guide the detergent and inlet water flow into the inner cylinder 320 after they are mixed in the chamber 352, thereby dispensing the detergent.

[0297] In this embodiment, chamber 352 is used to form a water mixing structure between detergent and incoming water flow, so as to further enhance the full dissolution of detergent, thereby improving the cleaning effect and reducing residue on clothes.

[0298] Furthermore, the gas-liquid conveying component 350 is provided with at least one set of water outlets 353 on the surface facing the bottom of the inner cylinder 320 for directional conveying of the incoming water flow.

[0299] The shape of the gas-liquid conveying component 350 is adapted to the bottom of the inner cylinder 320. In this embodiment, the gas-liquid conveying component 350 is disc-shaped; different shapes of gas-liquid conveying components 350 can be designed as needed.

[0300] In this embodiment, a fluid passage 343 is formed inside the sealing ring assembly 340, and a chamber 352 is formed in the gas-liquid conveying component 350. The fluid passage 343 is connected to the chamber 352, and the chamber 352 is connected to at least one set of water outlets 353. After the water flows into the chamber 352 through the fluid passage 343, the water flows directly sprayed into the inner drum 320 along the axial direction through the water outlets 353, further expanding the coverage of the water flow, so that the clothes are soaked faster and the detergent dissolves more quickly.

[0301] It should be noted that multiple fluid passages 343 can be formed within the sealing ring assembly 340, corresponding to multiple chambers 352 formed within the gas-liquid conveying component 350. Each fluid passage 343 is connected to at least one chamber 352, enabling multiple functions such as water inlet flow and detergent dispensing.

[0302] Furthermore, the arrangement of the outlets 353 in each group matches the arrangement of the drain holes 321 at the bottom of the inner cylinder 320 to ensure the smoothness of the water jet.

[0303] In some embodiments, each set of outlets 353 has at least two water outlet directions to deliver the incoming water flow to different positions inside the inner cylinder 320; by combining outlets 353 with different water outlet directions, the water flow coverage range can be further expanded to cover the entire area of ​​the inner cylinder 320 in multiple dimensions.

[0304] In some embodiments, the tripod 330 forms a positioning structure for limiting the position of the gas-liquid transport member 350; when the gas-liquid transport member 350 is assembled with the tripod 330, the outlet 353 is aligned with the drain hole 321.

[0305] Furthermore, the outlet 353 protrudes from the surface of the gas-liquid conveying component 350 to mate with the drain hole 321. Specifically, when the gas-liquid conveying component 350 and the tripod 330 are installed, the outlet 353 can extend into the drain hole 321 to connect with the internal environment of the inner cylinder 320, so that the incoming water flow can enter the inner cylinder 320 more quickly and smoothly.

[0306] In some embodiments, the outlet 353 further includes a switch structure for opening or closing the outlet 353 to achieve dynamic and precise control of the inlet water flow path; further, the switch structure is a one-way valve.

[0307] In some embodiments, the inner wall of the inner cylinder 320 is provided with lifting ribs 322, and the gas-liquid conveying component 350 is connected to the lifting ribs 322 to spray water through the lifting ribs 322; further, the gas-liquid conveying component 350 includes at least one conveying pipe 351, and at least one of the conveying pipes 351 extends into the interior of the lifting ribs 322 to spray water onto the clothes inside the cylinder through the lifting ribs 322.

[0308] Furthermore, the number of conveying pipes 351 matches the number of lifting ribs 322, and each conveying pipe 351 extends into a corresponding lifting rib 322.

[0309] Furthermore, the lifting rib 322 has a plurality of through holes 3221 for allowing water to flow through, so as to form a spray water inlet.

[0310] This utility model embodiment also provides a garment care device 1, including a cylindrical body as described in the above embodiment. This embodiment not only efficiently and reliably completes the rotary dynamic sealing function, but also integrates a continuous closed fluid passage 343 between the mutually fitting first annular member 341 and second annular member 342, thus integrating both rotary sealing and fluid delivery functions during rotation, thereby enhancing the functional diversity of the garment care device 1 and optimizing the user experience.

[0311] Example 4

[0312] The design of the washing machine's circulating water outlet directly affects detergent dissolution efficiency, rinsing effect, and energy consumption. Currently, the circulating water outlet is generally located at a specific position on the outer drum to form a fixed, single direction of circulating water flow. When the inner drum rotates, the clothes may not be evenly exposed to the water flow due to changes in position, resulting in detergent residue or incomplete rinsing. For example, when water comes out from the top of the outer drum, the strong water flow may cause clothes to tangle and increase friction. Furthermore, the fixed water flow may only cover the upper half of the clothes in the inner drum, leaving the lower half unrinsed. The high-speed water flow impacting the inner drum wall can also easily generate significant noise. In addition, to ensure that all clothes in the drum are exposed to the water flow, a fixed circulating water outlet may require more water circulation, especially after washing stubborn stains, as the increased number of water circulations leads to longer rinsing times and higher water consumption.

[0313] Therefore, this embodiment of the invention also provides a cylindrical body for a garment care device 1, combined with... Figures 1-12 , Figure 15 As shown, it includes:

[0314] Inner cylinder 420; outer cylinder 410;

[0315] Tripod 430 is fixedly connected to the bottom of the inner cylinder 420 to transmit rotational driving force to the inner cylinder 420; and the end of the tripod 430 extends axially along the inner cylinder 420 and passes through the outer cylinder 410 to form a rotation shaft 431.

[0316] The sealing ring assembly 440 includes a first annular member 441 and a second annular member 442 whose end faces are tightly fitted together. The first annular member 441 is fixed to the rotating shaft 431, and the second annular member 442 is installed on the outer cylinder 410. When the first annular member 441 rotates with the rotating shaft 431, it can abut against the second annular member 442 to form a dynamic seal at the end of the rotating shaft 431. At least one continuously closed fluid passage 443 is formed between the first annular member 441 and the second annular member 442 to connect the liquid environment inside and outside the cylinder when the end of the rotating shaft 431 is sealed, that is, to deliver washing water into the cylinder during the rotation of the inner cylinder 420.

[0317] The circulating water path 460 has one end installed with the second annular component 442 and connected to the fluid passage 443, and the other end connected to the bottom of the outer cylinder 410.

[0318] A gas-liquid conveying component 450 is installed with the first annular component 441; and the gas-liquid conveying component 450 is connected to the fluid passage 443 and the inner cylinder 420 respectively to form a circulating water guiding structure.

[0319] The washing water in the outer drum 410 is drawn into the fluid passage 443 through the circulating water passage 460, and then the gas-liquid conveying component 450 conveys the washing water into the inner drum 420, forming the circulating water structure of the garment care device 1.

[0320] This embodiment not only efficiently and reliably completes the rotational dynamic sealing function, but also integrates a continuous closed fluid passage 443 between the mutually fitting first annular member 441 and second annular member 442, thus integrating both rotational sealing and fluid delivery functions in the rotational state. This enhances the functional diversity of the garment care device 1 and optimizes the user experience. The fluid passage 443 is embedded inside the sealing ring assembly 440, avoiding excessive additional space occupation and minimizing space occupancy.

[0321] The assembly structure that fixes the first annular component 441 to the rotating shaft 431 and the second annular component 442 to the outer cylinder 410 provides a stable sealing pressure between the first annular component 441 and the second annular component 442 and a stable pressure boundary for the fluid passage 443. On the other hand, it effectively simplifies the assembly method of the sealing ring assembly 440, making the axial structure more compact.

[0322] Compared to traditional circulating water flow methods, the circulating water flow from the fluid passage 443 is redirected by the gas-liquid conveyor 450 and transported axially along the inner drum 420 into the inner drum 420. Combined with the centrifugal force generated by the rotation of the inner drum 420, it can better ensure that the water flow is fully and evenly guided to the rolling clothes, improving the penetration of the washing water and the contact efficiency with the clothes. In addition, the strong water flow impact or spray helps to penetrate multiple layers of clothing, better rinse stains, rinse away residual detergent, and improve the washing cleanliness and rinsing efficiency.

[0323] In addition, in this embodiment, the circulating water path 460 is directly connected from the sealing ring assembly 440 to the bottom of the outer cylinder 410, which is short and compact. The water flows directly to the delivery point through the fluid passage 443 inside the sealing ring assembly 440, which helps to quickly establish and maintain effective water circulation and improve the overall circulation efficiency.

[0324] In some embodiments, the circulating water path 460 includes a first pipe 461, a second pipe 462, and a pump body 463; wherein,

[0325] The first pipe 461 is located at the bottom of the side wall of the outer cylinder 410;

[0326] The second pipe 462 is located at the bottom of the outer cylinder 410, and one end of the second pipe 462 is connected to the first pipe 461, and the other end is connected to the fluid passage 443;

[0327] The pump body 463 is connected to the first pipe 461 and is used to draw washing water from the outer cylinder 410.

[0328] Specifically, the pump body 463 is disposed at the bottom of the side wall of the outer cylinder 410 and is detachably installed with the outer cylinder 410; the pump body 463 draws the washing water in the outer cylinder 410 and transports it to the first pipe 461. The washing water flows sequentially through the first pipe 461 and the second pipe 462 into the fluid passage 443, and is then transported back to the outer cylinder 410 by the gas-liquid conveying component 450, forming a washing water circulation.

[0329] Furthermore, the first pipe 461 and the outer cylinder 410 are integrally formed, which can eliminate the need for complex assembly structures, simplify the overall structure, improve structural strength, and provide better sealing, ensuring the precise directional delivery of washing water.

[0330] Furthermore, the second pipe 462 includes a circulation channel 4621 formed at the bottom of the outer cylinder 410 and a circulation cover 4622 covering the circulation channel 4621; wherein, the circulation channel 4621 extends to the second annular member 442 and communicates with the fluid passage 443. Specifically, the circulation channel 4621 is integrally formed with the outer cylinder 410, possessing good structural strength and contributing to structural stability; furthermore, the circulation cover 4622 is detachably connected to the circulation channel 4621 by screws or snap-fit ​​structures, facilitating maintenance or cleaning; for example, it can be opened to clean deposits in the circulation channel 4621, preventing blockages, etc.

[0331] Furthermore, a filter structure is provided at the pump body 463 to effectively prevent excessive deposits from forming in the circulating water path 460, fluid passage 443, and gas-liquid conveying component 450, thus avoiding blockage. Furthermore, the filter structure is detachably connected to the pump body 463 for easy cleaning and replacement.

[0332] In some other embodiments, the outer drum 410 includes a drain outlet, and the circulating water path 460 is connected to the drain outlet. For example, when the garment care device 1 enters the rinsing stage, the circulating water path 460 is connected to the drain outlet, and the washing water enters the circulating water path 460 through the drain outlet. The circulating water path 460 then transports the washing water to the fluid passage 443, and finally the gas-liquid conveying component 450 transports the washing water back to the outer drum 410, thereby realizing the circulation of washing water.

[0333] In some embodiments, the gas-liquid conveying component 450 is provided with at least one set of water outlets 453 on the surface facing the bottom of the inner cylinder 420 for directional conveying of circulating water.

[0334] The shape of the gas-liquid conveying component 450 is adapted to the bottom of the inner cylinder 420. In this embodiment, the gas-liquid conveying component 450 is disc-shaped; different shapes of gas-liquid conveying components 450 can be designed as needed.

[0335] Specifically, the gas-liquid conveying component 450 has at least one chamber 452 inside; a fluid passage 443 communicates with at least one chamber 452; the chamber 452 is used to form a transition space for circulating water flow.

[0336] In this embodiment, a fluid passage 443 is formed inside the sealing ring assembly 440, and a chamber 452 is formed by the gas-liquid conveying component 450. The fluid passage 443 is connected to the chamber 452, and the chamber 452 is connected to at least one set of water outlets 453. After the circulating water enters the chamber 452 through the fluid passage 443, the circulating water is sprayed directly along the axial direction of the inner drum 420 through the water outlets 453, which creates a stronger rinsing force on the clothes and improves the rinsing efficiency and washing effect.

[0337] It should be noted that when multiple fluid passages 443 are formed within the sealing ring assembly 440, multiple chambers 452 are formed within the gas-liquid conveying component 450, and each fluid passage 443 is connected to at least one chamber 452.

[0338] Furthermore, the arrangement of the outlets 453 in each group matches the arrangement of the drain holes 421 at the bottom of the inner cylinder 420 to ensure the smoothness of the circulating water spray and the spray coverage.

[0339] In some embodiments, each set of outlets 453 has at least two water outlet directions to deliver circulating water to different locations inside the inner cylinder 420; by combining outlets 453 with different water outlet directions, the water flow coverage range can be further expanded to cover the entire area of ​​the inner cylinder 420 in multiple dimensions.

[0340] In some embodiments, the tripod 430 forms a positioning structure for limiting the position of the gas-liquid transport member 450; when the gas-liquid transport member 450 is assembled with the tripod 430, the outlet 453 is aligned with the drain hole 421.

[0341] Furthermore, the outlet 453 protrudes from the surface of the gas-liquid conveying component 450 to mate with the drain hole 421. Specifically, when the gas-liquid conveying component 450 and the tripod 430 are installed, the outlet 453 can extend into the drain hole 421 to connect with the internal environment of the inner cylinder 420, so that the circulating water can enter the inner cylinder 420 more quickly and smoothly.

[0342] In some embodiments, the outlet 453 further includes a switch structure for opening or closing the outlet 453 to achieve dynamic and precise control of the circulating water flow path. Further, the switch structure may be a pump body 463 or a valve body, etc.

[0343] In some embodiments, the inner wall of the inner cylinder 420 is provided with lifting ribs 422, and the gas-liquid conveying component 450 is connected to the lifting ribs 422 to spray water through the lifting ribs 422; further, the gas-liquid conveying component 450 includes at least one conveying pipe 451, and at least one of the conveying pipes 451 extends into the interior of the lifting ribs 422 to spray water onto the clothes inside the cylinder through the lifting ribs 422.

[0344] Furthermore, the number of conveying pipes 451 matches the number of lifting ribs 422, and each conveying pipe 451 extends into a corresponding lifting rib 422.

[0345] Furthermore, the lifting rib 422 is provided with a plurality of third through holes 4221 to allow circulating water to flow through, so as to form a spraying effect.

[0346] This embodiment of the invention also provides a garment care device 1, including a cylindrical body as described in Embodiment 6. This embodiment not only efficiently and reliably performs the rotary dynamic sealing function, but also integrates a continuous closed fluid passage 443 between the mutually fitting first annular member 441 and second annular member 442, thus integrating both rotary sealing and fluid delivery functions during rotation. This enhances the functional diversity of the garment care device 1 and optimizes the user experience.

[0347] Example 5

[0348] To improve the efficiency of washing machine laundry or to perform specific functions, it is often necessary to introduce washing water during the rotation of the inner drum, such as to perform spraying or defoaming operations. Currently, the mainstream technology for implementing spraying functions in washing machines mainly relies on setting spray nozzles at specific locations on the outer drum for fixed and unidirectional spraying. However, the spraying direction of fixed-position spray nozzles is preset and cannot move with the clothes, which can easily create spray blind spots. It is difficult to ensure that the sprayed water flow can effectively cover all areas of the inner drum, resulting in poor spray uniformity, low defoaming efficiency, increased energy consumption, and reduced user experience.

[0349] This utility model embodiment provides a cylindrical body for a garment care device 1, combined with... Figures 1-12 , Figure 16 As shown, it includes:

[0350] Inner cylinder 520; outer cylinder 510;

[0351] Tripod 530 is fixedly connected to the bottom of the inner cylinder 520 to transmit rotational driving force to the inner cylinder 520; and the end of the tripod 530 extends axially along the inner cylinder 520 and passes through the outer cylinder 510 to form a rotation shaft 531.

[0352] The sealing ring assembly 540 includes a first annular member 541 and a second annular member 542 whose end faces are tightly fitted together. The first annular member 541 is fixed to the rotating shaft 531, and the second annular member 542 is installed on the outer cylinder 510. When the first annular member 541 rotates with the rotating shaft 531, it can abut against the second annular member 542 to form a dynamic seal at the end of the rotating shaft 531. At least one continuously closed fluid passage 543 is formed between the first annular member 541 and the second annular member 542 within the sealing ring assembly 540 to connect the liquid environment inside and outside the cylinder when the end of the rotating shaft 531 is sealed, that is, to deliver washing water into the cylinder during the rotation of the inner cylinder 520.

[0353] A spray water path 560 is installed with the second annular member 542 and communicates with at least one of the fluid passages 543 to provide a spray water flow to the fluid passage 543;

[0354] A gas-liquid conveying component 550 is installed with the first annular component 541; and the gas-liquid conveying component 550 is connected to the fluid passage 543 and the inner cylinder 520 respectively to form a guide structure for spray water.

[0355] The gas-liquid conveying component 550 is configured to receive the washing water flowing out of the fluid passage 543 and spray it into the inner drum 520 to form the spray / defoaming structure of the garment care device 1.

[0356] This embodiment not only efficiently and reliably completes the rotational dynamic sealing function, but also integrates a continuous closed fluid passage 543 between the mutually fitting first annular member 541 and second annular member 542, thus integrating both rotational sealing and fluid delivery functions during rotation. This enhances the functional diversity of the garment care device 1 and optimizes the user experience. The fluid passage 543 is embedded inside the sealing ring assembly 540, avoiding excessive additional space occupation and minimizing space usage.

[0357] The assembly structure, which fixes the first annular component 541 to the rotating shaft and the second annular component 542 to the outer cylinder 510, provides a stable sealing pressure between the first annular component 541 and the second annular component 542 and a stable pressure boundary for the fluid passage 543. On the other hand, it effectively simplifies the assembly method of the sealing ring assembly 540, making the axial structure more compact.

[0358] Compared to the traditional top spraying method, this embodiment uses the gas-liquid conveyor 550 to redirect the spray water flow from the fluid passage 543 and deliver it axially along the inner drum 520 into the inner drum 520. Combined with the centrifugal force generated by the rotation of the inner drum 520, a three-dimensional spraying effect can be generated inside the inner drum 520. On the one hand, it can directly impact the foam layer during defoaming, achieving efficient active defoaming, effectively preventing overflow, and improving rinsing efficiency and cleanliness. On the other hand, this spraying method can enable the washing water to powerfully penetrate the areas of piled or tangled clothes, expanding the spray coverage area.

[0359] In some embodiments, the spray water path 560 is connected to the water inlet system and / or circulating water system and / or dispensing device of the garment care device 1.

[0360] For example, during the water intake stage of the garment care device 1, the spray water path 560 is connected to the water intake system, and the incoming water is injected into the inner drum 520 in a spray manner, directly acting on the clothes. On the one hand, it can quickly soak the dry clothes before the washing begins, enhancing the pre-wetting effect. On the other hand, it can accelerate the dissolution of detergent and facilitate the penetration of clothing fibers.

[0361] For example, during the rinsing stage of the garment care device 1, the spray water path 560 is connected to the circulating water system, and the circulating water is injected into the inner drum 520 in a spray manner to rinse the surface of the clothes. The spray water impact carries away the detergent foam, while reducing the number of rinsing times. In addition, the spray water path 560 can create a dynamic water environment inside the drum during the rinsing stage, which significantly improves rinsing efficiency and reduces detergent residue.

[0362] For example, during the detergent dispensing stage of the garment care device 1, the spray water path 560 can be connected to the dispensing device to inject the mixture of detergent and water into the inner drum 520 by spraying, which can quickly penetrate the garment fibers, enhance stain dissolution, and improve the garment cleaning effect.

[0363] In some embodiments, the gas-liquid conveying component 550 is provided with at least one set of nozzles 553 on the surface facing the bottom of the inner drum 520 for directional delivery of spray water. By providing nozzles 553, the spray water can provide all-round spray coverage to the inner drum 520. The spray water diffuses from the axial center of the inner drum 520 in a circumferential direction, and with the centrifugal force, forms a three-dimensional rinsing effect inside the inner drum 520, which has stronger penetrating power to effectively break down stubborn stains on clothing or defoam the foam layer.

[0364] The shape of the gas-liquid conveying component 550 is adapted to the bottom of the inner cylinder 520. In this embodiment, the gas-liquid conveying component 550 is disc-shaped; different shapes of gas-liquid conveying components 550 can be designed as needed.

[0365] Specifically, the gas-liquid conveying component 550 has at least one chamber 552 inside; a fluid passage 543 communicates with at least one of the chambers 552; the chamber 552 is used to form a transition space for the spray water flow.

[0366] In this embodiment, a fluid passage 543 is formed inside the sealing ring assembly 540, and a chamber 552 is formed in the gas-liquid conveying component 550. The fluid passage 543 is connected to the chamber 552, and the chamber 552 is connected to at least one set of nozzles 553. After the spray water enters the chamber 552 through the fluid passage 543, the spray water is sprayed directly along the axial direction of the inner cylinder 520 through the nozzles 553.

[0367] It should be noted that multiple fluid passages 543 can be formed within the sealing ring assembly 540, corresponding to multiple chambers 552 formed within the gas-liquid conveying component 550, and each fluid passage 543 is connected to at least one chamber 552.

[0368] In some embodiments, each group of nozzles 553 includes at least a large-diameter nozzle 553 and a small-diameter nozzle 553 to spray different amounts of water for spraying / defoaming. Specifically, through the coordinated operation of multiple diameter nozzles 553, the large-diameter nozzle 553 has the characteristics of large flow rate and wide coverage, washing clothes with a large area of ​​water flow; the small-diameter nozzle 553 has the characteristics of high flow rate and strong penetration, which can directly hit the gaps in clothing fibers, break down stains, and impact the foam layer at high speed to achieve rapid defoaming.

[0369] In some other embodiments, the nozzle 553 is a variable diameter nozzle 553 with switchable diameter, which further realizes fine control of water flow and achieves multi-dimensional optimization of washing effect. It not only meets the needs of efficient cleaning, but also can adapt to different types of clothing and different washing scenarios by adjusting the water flow characteristics.

[0370] In some embodiments, each set of nozzles 553 has at least two water outlet directions for spraying different locations inside the inner cylinder 520; by combining water outlets with different water outlet directions, the water flow coverage range can be further expanded to cover the entire area of ​​the inner cylinder 520 in multiple dimensions.

[0371] Furthermore, the water outlet direction of each set of nozzles 553 is adjustable, enabling dynamic control of the water flow direction and further refining the management of the washing process. The spray water flow strategy is dynamically adjusted according to the type of clothing, defoaming stage, etc.

[0372] In some embodiments, the arrangement of the nozzles 553 in each group matches the arrangement of the drain holes 521 at the bottom of the inner cylinder 520 to ensure smooth spraying and spray coverage.

[0373] In some embodiments, the tripod 530 forms a positioning structure for limiting the position of the gas-liquid delivery member 550; when the gas-liquid delivery member 550 is assembled with the tripod 530, the nozzle 553 is aligned with the drain hole 521.

[0374] Furthermore, the nozzle 553 protrudes from the surface of the gas-liquid conveying component 550 to mate with the drain hole 521. Specifically, when the gas-liquid conveying component 550 and the tripod 530 are installed, the nozzle 553 can extend into the drain hole 521 to connect with the internal environment of the inner cylinder 520, so that the spray water can enter the inner cylinder 520 more quickly and smoothly.

[0375] In some embodiments, the nozzle 553 further includes a switch structure for opening or closing the nozzle 553 to achieve dynamic and precise control of the spray water flow path.

[0376] In some embodiments, the inner wall of the inner cylinder 520 is provided with lifting ribs 522, and the gas-liquid conveying component 550 is connected to the lifting ribs 522 to spray water through the lifting ribs 522; further, the gas-liquid conveying component 550 includes at least one conveying pipe 551, and at least one of the conveying pipes 551 extends into the interior of the lifting ribs 522.

[0377] Furthermore, the number of conveying pipes 551 matches the number of lifting ribs 522, and each conveying pipe 551 extends into a corresponding lifting rib 522.

[0378] Furthermore, the lifting rib 522 is provided with a plurality of fourth through holes 5221 for allowing spray water to flow through, so as to spray the inside of the inner cylinder 520.

[0379] This utility model embodiment also provides a garment care device 1, including the cylindrical body of the garment care device 1 described in the above embodiment. This embodiment not only efficiently and reliably completes the rotary dynamic sealing function, but also integrates a continuous closed fluid passage 543 between the mutually fitting first annular member 541 and second annular member 542, thus integrating both rotary sealing and fluid delivery functions during rotation, thereby enhancing the functional diversity of the garment care device 1 and optimizing the user experience.

[0380] This utility model embodiment also provides a defoaming method for a garment care device, combined with... Figure 17 As shown, the garment care device described above is controlled to perform the following steps:

[0381] S51. Obtain defoaming instructions; wherein, the defoaming instructions include basic defoaming instructions and cyclic defoaming instructions; for example, the foam height inside the inner drum can be identified by an image acquisition device, and a defoaming instruction is generated when the height reaches a warning value; wherein, the defoaming instructions are activated when foam overflows during the main wash stage, during the settling and draining period of the rinsing stage, or before the dehydration stage; in some optional embodiments, the basic defoaming instruction is activated when foam overflows during the main wash stage or before the dehydration stage, and the cyclic defoaming instruction is activated during the rinsing stage.

[0382] S52. When the defoaming command is the basic defoaming command, control the gas-liquid conveying component to spray tap water into the inner cylinder for defoaming; specifically, when spraying tap water, control the spray water path to connect with the water inlet system of the garment care device so as to spray into the cylinder through the gas-liquid conveying component.

[0383] S53. When the defoaming command is a circulating defoaming command, the gas-liquid conveying component is controlled to spray washing water into the inner drum for defoaming; specifically, when spraying circulating water, the spraying water path is controlled to be connected to the circulating water system of the garment care device so as to spray into the drum through the gas-liquid conveying component.

[0384] This embodiment uses a gas-liquid conveying component to redirect the spray water flow from the fluid passage and deliver it axially into the inner cylinder. Combined with the centrifugal force generated by the rotation of the inner cylinder, a three-dimensional spraying effect can be generated inside the inner cylinder. When performing defoaming, it directly impacts the foam layer, achieving efficient active defoaming, effectively preventing overflow foam, and improving rinsing efficiency and cleanliness.

[0385] In some implementations, combined Figure 18 As shown, it also includes the following steps:

[0386] S54. Detect the foam condition inside the inner cylinder; for example, detect the foam concentration and distribution inside the inner cylinder using a foam sensor installed in the inner cylinder.

[0387] S55. Adjust the spraying mode of the gas-liquid conveying component according to the foam situation; wherein, the spraying mode includes spraying direction and spraying intensity. For example, when the foam concentration is less than a first threshold, it is judged as low concentration and a normal spraying mode is used; when the foam concentration is greater than or equal to the first threshold, it is judged as medium concentration and the spraying intensity is increased; when the foam concentration is greater than or equal to a second threshold, it is judged as high concentration and both the spraying intensity and spraying direction are increased.

[0388] In some embodiments, the step of adjusting the spray pattern of the gas-liquid conveying component includes:

[0389] The spray direction of the gas-liquid conveying component can be dynamically changed by adjusting the rotation mode of the inner cylinder.

[0390] In some other embodiments, the step of adjusting the spray pattern of the gas-liquid conveying component includes:

[0391] The spray intensity of the gas-liquid conveying component can be dynamically changed by adjusting the spray duration and / or spray flow rate.

[0392] Example 6

[0393] To enhance washing machine functionality, existing solutions include incorporating a fresh air system. This effectively improves the washing environment, eliminates odors and bacteria, and provides a healthier and more efficient washing experience. Currently, however, the fresh air vents are typically located in specific positions on the outer drum, creating a fixed and singular airflow path. This makes it difficult to ensure that fresh air effectively covers all areas of the inner drum, thus reducing the user experience.

[0394] This utility model embodiment also provides a cylindrical body for a garment care device 1, combined with... Figures 1-12 , Figures 19-20 As shown, it includes:

[0395] Inner cylinder 620; outer cylinder 610;

[0396] Tripod 630 is fixedly connected to the bottom of the inner cylinder 620 to transmit rotational driving force to the inner cylinder 620; and the end of the tripod 630 extends axially along the inner cylinder 620 and passes through the outer cylinder 610 to form a rotation shaft 631.

[0397] The sealing ring assembly 640 includes a first annular member 641 and a second annular member 642 whose end faces are tightly fitted together. The first annular member 641 is fixed to the rotating shaft 631, and the second annular member 642 is installed on the outer cylinder 610. When the first annular member 641 rotates with the rotating shaft 631, it can abut against the second annular member 642 to form a dynamic seal at the end of the rotating shaft 631. At least one continuously closed fluid passage 643 is formed between the first annular member 641 and the second annular member 642 within the sealing ring assembly 640 to connect the gas environment inside and outside the cylinder when the end of the rotating shaft 631 is sealed, that is, to deliver gas to the inside / outside of the outer cylinder 610 during the rotation of the inner cylinder 620.

[0398] The fresh air passage 660 is installed with the second annular component 642, and one end of the fresh air passage 660 is connected to at least one of the fluid passages 643, and the other end is connected to the fresh air device 670 of the garment care device 1, so as to provide fresh air flow to the fluid passages 643.

[0399] A gas-liquid conveying component 650 is installed with the first annular component 641; and the gas-liquid conveying component 650 is connected to the fluid passage 643 and the inner cylinder 620 respectively to form a gas guiding structure.

[0400] When the garment care device 1 is in fresh air mode, the gas-liquid conveying component 650 connects the internal environment of the outer cylinder 610 and the fresh air passage 660 to exchange gases inside and outside the cylinder.

[0401] This embodiment not only efficiently and reliably completes the rotational dynamic sealing function, but also integrates a continuous closed fluid passage 643 between the mutually fitting first annular member 641 and second annular member 642, thus integrating both rotational sealing and fluid delivery functions during rotation. This enhances the functional diversity of the garment care device 1 and optimizes the user experience. The fluid passage 643 is embedded inside the sealing ring assembly 640, avoiding excessive additional space occupation and minimizing space usage.

[0402] The assembly structure that fixes the first annular component 641 to the rotating shaft and the second annular component 642 to the outer cylinder 610 provides a stable sealing pressure between the first annular component 641 and the second annular component 642 and a stable pressure boundary for the fluid passage 643. On the other hand, it effectively simplifies the assembly method of the sealing ring assembly 640, making the axial structure more compact.

[0403] The gas-liquid conveying component 650 redirects fresh air from the fluid passage 643 and delivers it axially into the inner drum 620, removing any odors and bacteria that may be present inside the drum. This also ensures good ventilation during use, preventing odors from developing when clothes are temporarily stored in the inner drum 620. The axially introduced fresh air, combined with the centrifugal force of the rotating inner drum 620, better guides the airflow to form a more uniform flow field inside the drum, effectively increasing the contact and exchange efficiency between the air inside the drum and the fresh air outside. This alleviates odors and bacterial growth caused by the closed environment, keeps the drum clean and hygienic, and improves the user experience.

[0404] In some embodiments, the outer cylinder 610 is provided with an exhaust port, through which fresh air is introduced into the cylinder and then discharged to the outside.

[0405] In some embodiments, the sealing ring assembly 640 is provided with at least two fluid passages 643. One fluid passage 643 is connected to the fresh air passage 660, and the other fluid passage 643 is connected to the exhaust structure of the garment care device 1 to form a fresh air loop. Specifically, the two fluid passages 643 are connected to the gas-liquid conveying component 650, which forms a guiding structure for gas exchange within the cylinder; that is, after fresh air enters the cylinder along one fluid passage 643, it can be discharged outward through the other fluid passage 643; wherein, the gas-liquid conveying component 650 is divided into different chambers 652 to communicate with the corresponding fluid passages 643.

[0406] In some embodiments, the fresh air duct 660 is embedded in the bottom of the outer cylinder 610.

[0407] In some optional embodiments, the fresh air duct 660 includes a fresh air pipe embedded in the bottom of the outer cylinder 610; integrating the fresh air pipe into the wall thickness of the bottom of the outer cylinder 610 significantly saves axial and radial space, maximizes space utilization, and makes the structure compact; furthermore, the fresh air pipe is hidden inside the bottom of the outer cylinder 610, completely avoiding the risk of interference between exposed pipes and the rotating shaft 631, and improving operational reliability.

[0408] In some alternative embodiments, the fresh air duct 660 includes a fresh air channel 661 formed at the bottom of the outer cylinder 610 and a fresh air cover 662 covering the fresh air channel 661; this simplifies the manufacturing process and reduces manufacturing costs. Specifically, the fresh air channel 661 is integrally formed with the outer cylinder 610, possessing good structural strength and contributing to structural stability. Furthermore, the fresh air cover 662 is detachably connected to the fresh air channel 661 via screws or snap-fit ​​structures, which facilitates maintenance or cleaning.

[0409] In some embodiments, the fresh air passage 660 extends from the second annular member 642 to the bottom edge of the outer cylinder 610, and forms a vent 611 at the bottom of the outer cylinder 610. The vent 611 is used to assemble with the fresh air device 670. Specifically, the vent 611 protrudes axially from the bottom surface of the outer cylinder 610, and the vent 611 is used to communicate with the fresh air delivery duct 671 of the fresh air device 670. The fresh air delivery duct 671 can be installed with a fresh air fan 672 to introduce fresh air. The fresh air is introduced into the fresh air delivery duct 671 by the fresh air fan 672, and then delivered to the vent 611 to enter the fresh air passage 660.

[0410] In some embodiments, the system further includes a humidity sensor and / or a temperature sensor, or a temperature and humidity sensor, connected to the fresh air duct 660 to obtain information about the environment inside the duct. For example, by installing a humidity sensor in the fresh air duct 660 or inside the duct, the humidity of the fresh air and the humidity of the air inside the duct can be detected in real time to ensure that the clothes temporarily stored inside the duct maintain a suitable humidity. As another example, by installing a temperature sensor in the fresh air duct 660 or inside the duct, the temperature of the fresh air and the temperature inside the duct can be detected in real time to ensure the stability of the ambient temperature inside the duct and to prevent the clothes temporarily stored inside the duct from developing odors or bacteria. As yet another example, the humidity sensor and the temperature sensor can be used in conjunction, or a temperature and humidity sensor can be used, to simultaneously monitor the temperature and humidity inside the duct.

[0411] In some embodiments, it further includes: an aromatherapy module connected to the fresh air path 660 to achieve fragrance care for clothes, while also achieving sterilization and mite removal effects, thereby enhancing the user experience.

[0412] In some embodiments, the gas-liquid conveying component 650 is provided with at least one set of ventilation holes 653 on the surface of the inner cylinder 620 facing the bottom of the cylinder, for directional delivery of fresh air.

[0413] The shape of the gas-liquid conveying component 650 is adapted to the bottom of the inner cylinder 620. In this embodiment, the gas-liquid conveying component 650 is disc-shaped; different shapes of gas-liquid conveying components 650 can be designed as needed.

[0414] Specifically, the gas-liquid conveying component 650 has at least one chamber 652 inside; a fluid passage 643 communicates with at least one chamber 652; the chamber 652 is used to form a transition space for fresh air flow; in some embodiments, a fluid passage 643 is formed inside the sealing ring assembly 640, the gas-liquid conveying component 650 forms a chamber 652, the fluid passage 643 is connected to the chamber 652, and the chamber 652 is connected to at least one set of ventilation holes 653; after fresh air enters the chamber 652 through the fluid passage 643, the fresh air is directly conveyed along the axial direction of the inner cylinder 620 through the ventilation holes 653, which can form a more uniform flow field inside the cylinder and further accelerate the exchange rate of air inside and outside the cylinder.

[0415] It should be noted that multiple fluid passages 643 can be formed within the sealing ring assembly 640, corresponding to multiple chambers 652 formed within the gas-liquid conveying component 650, and each fluid passage 643 is connected to at least one chamber 652.

[0416] Furthermore, the arrangement of the ventilation holes 653 matches the arrangement of the drainage holes 621 at the bottom of the inner cylinder 620 to ensure the fresh air delivery rate.

[0417] In some embodiments, the tripod 630 forms a positioning structure for limiting the position of the gas-liquid transport member 650; when the gas-liquid transport member 650 is assembled with the tripod 630, the ventilation hole 653 is aligned with the drain hole 621.

[0418] Furthermore, the ventilation hole 653 protrudes from the surface of the gas-liquid conveying component 650 to mate with the drain hole 621. Specifically, when the gas-liquid conveying component 650 and the tripod 630 are installed, the ventilation hole 653 can extend into the drain hole 621 to connect with the internal environment of the inner cylinder 620, so that fresh air can enter the inner cylinder 620 more quickly and smoothly.

[0419] In some embodiments, a damper is provided at the ventilation hole 653 to open or block the fresh air flow path, thereby achieving dynamic and precise control of the fresh air flow path.

[0420] In some embodiments, the inner wall of the inner cylinder 620 is provided with a lifting rib 622, and the gas-liquid conveying component 650 is connected to the lifting rib 622 to introduce fresh air through the lifting rib 622; further, the gas-liquid conveying component 650 includes at least one conveying pipe 651, and at least one of the conveying pipes 651 extends into the interior of the lifting rib 622 to introduce fresh air into the cylinder through the lifting rib 622.

[0421] Furthermore, the number of conveying pipes 651 matches the number of lifting ribs 622, and each conveying pipe 651 extends into a corresponding lifting rib 622. Furthermore, each lifting rib 622 has a plurality of through holes 6221 for allowing fresh air to pass through.

[0422] This utility model embodiment also provides a garment care device 1, including a cylindrical body as described in the above embodiment. This embodiment not only efficiently and reliably completes the rotary dynamic sealing function, but also integrates a continuous closed fluid passage 643 between the mutually fitting first annular member 641 and second annular member 642, thus integrating both rotary sealing and fluid delivery functions during rotation, thereby enhancing the functional diversity of the garment care device 1 and optimizing the user experience.

[0423] Example 7

[0424] In the present technology, clothes dryers or washing machines with drying functions are one of the indispensable home appliances in modern households, providing people with a solution for fast and even drying of clothes. However, the drying air vents in existing washing machines are generally located in a fixed position on the outer drum. The drying airflow is easily interfered with by the rotation of the inner drum, and the airflow is concentrated in a local area. Areas where clothes are piled up may not be effectively exposed to hot air, resulting in uneven drying. Furthermore, to ensure that all clothes in the drum are exposed to hot air, fixed drying air vents require longer drying time or higher heating power, leading to increased energy consumption.

[0425] This utility model embodiment also provides a cylindrical body for a garment care device 1, combined with... Figures 1-12 , Figures 21-22 As shown, it includes:

[0426] Inner cylinder 720; outer cylinder 710;

[0427] Tripod 730 is fixedly connected to the bottom of the inner cylinder 720 to transmit rotational driving force to the inner cylinder 720; and the end of the tripod 730 extends axially along the inner cylinder 720 and passes through the outer cylinder 710 to form a rotation shaft 731.

[0428] A sealing ring assembly 740 includes a first annular member 741 and a second annular member 742 whose end faces are tightly fitted together. The first annular member 741 is fixed to the rotating shaft 731, and the second annular member 742 is installed on the outer cylinder 710. When the first annular member 741 rotates with the rotating shaft 731, it can abut against the second annular member 742 to form a dynamic seal at the end of the rotating shaft 731. At least one continuously closed fluid passage 743 is formed between the first annular member 741 and the second annular member 742 within the sealing ring assembly 740 to connect the gas environment inside and outside the cylinder when the end of the rotating shaft 731 is sealed, that is, to deliver gas to the inside / outside of the outer cylinder 710 during the rotation of the inner cylinder 720.

[0429] A drying air passage 760 is installed with the second annular member 742, and one end of the drying air passage 760 is connected to at least one of the fluid passages 743, and the other end is connected to the drying device 770 of the garment care device 1, so as to provide drying airflow to the fluid passages 743.

[0430] A gas-liquid conveying component 750 is installed with the first annular component 741; and the gas-liquid conveying component 750 is connected to the fluid passage 743 and the inner cylinder 720 respectively to form a guiding structure for the drying airflow.

[0431] When the garment care device 1 is in drying mode, the gas-liquid conveying component 750 connects the internal environment of the cylinder and the drying air path 760 to introduce the drying airflow into the cylinder.

[0432] This embodiment not only efficiently and reliably completes the rotational dynamic sealing function, but also integrates a continuous closed fluid passage 743 between the mutually fitting first annular member 741 and second annular member 742, thus integrating both rotational sealing and fluid delivery functions during rotation. This enhances the functional diversity of the garment care device 1 and optimizes the user experience. The fluid passage 743 is embedded inside the sealing ring assembly 740, avoiding excessive additional space occupation and minimizing space usage.

[0433] The assembly structure, which fixes the first annular component 741 to the rotating shaft and the second annular component 742 to the outer cylinder 710, provides a stable sealing pressure between the first annular component 741 and the second annular component 742 and a stable pressure boundary for the fluid passage 743. On the other hand, it effectively simplifies the assembly method of the sealing ring assembly 740, making the axial structure more compact.

[0434] The drying airflow from the fluid passage 743 is redirected by the gas-liquid conveyor 750 and axially transported into the inner drum 720, forming an axially penetrating airflow path. This effectively accelerates the contact and replacement efficiency between the humid air and the dry drying airflow inside the drum, significantly speeding up the drying of clothes and shortening the drying time. The axially introduced drying airflow, combined with the rotation of the inner drum 720, can better guide the airflow to form a more uniform flow field inside the drum. On the other hand, as the clothes tumble during the rotation of the inner drum 720, the drying airflow can more easily penetrate the stacked clothes, reducing dead airflow angles and ensuring more uniform drying of clothes.

[0435] In some embodiments, the outer cylinder 710 is provided with a direct discharge port; when the dry drying airflow replaces the humid air inside the cylinder, the hot and humid air can be directly discharged to the outside from the direct discharge port.

[0436] In some alternative embodiments, the fluid passage 743 includes at least two fluid passages 743; wherein one fluid passage 743 is connected to the drying air passage 760, and the other fluid passage 743 is connected to the external atmosphere. Specifically, the two fluid passages 743 are connected to the gas-liquid conveying component 750, which forms a guide structure for the drying airflow; that is, after the dry drying airflow enters the drum along one fluid passage 743 to dry the clothes, the hot and humid air inside the drum can be directly discharged to the outside through the other fluid passage 743; wherein the gas-liquid conveying component 750 is divided into different chambers 752 to communicate with the corresponding fluid passages 743.

[0437] In some preferred embodiments, the fluid passage 743 includes at least two fluid passages 743; one fluid passage 743 is connected to the drying air passage 760, and the other fluid passage 743 is connected to the air inlet 772 of the drying device 770, forming a circulating air duct for drying airflow. Specifically, the drying air passage 760 is connected to the air outlet 773 of the drying device 770. After the dry drying airflow enters the drum along one fluid passage 743 to dry the clothes, the hot and humid air in the drum can be transported from the other fluid passage 743 to the air inlet 772 of the drying device 770. After condensation and heating, it enters the drying air passage 760 again through the air outlet 773 of the drying device 770, and is then transported back into the drum to continue the drying process; that is, the fluid passages 743 of the sealing ring assembly 740 form a circulating air duct structure for the drying device 770; wherein, the gas-liquid conveying component 750 is divided into different chambers 752 to communicate with the corresponding fluid passages 743.

[0438] In some embodiments, the drying air passage 760 is embedded in the bottom of the outer cylinder 710.

[0439] In some optional embodiments, the drying air path 760 includes a drying pipe embedded in the bottom of the outer cylinder 710; integrating the drying pipe into the wall thickness of the bottom of the outer cylinder 710 significantly saves axial and radial space, maximizes space utilization, and makes the structure compact; furthermore, the drying pipe is hidden inside the bottom of the outer cylinder 710, completely avoiding the risk of interference between the exposed pipe and the rotating shaft 731, and improving operational reliability.

[0440] In some alternative embodiments, the drying air passage 760 includes a drying channel 761 formed at the bottom of the outer cylinder 710 and a drying cover plate 762 covering the drying channel 761; this simplifies the manufacturing process and reduces manufacturing costs. Specifically, the drying channel 761 is integrally formed with the outer cylinder 710, possessing good structural strength and contributing to structural stability. Furthermore, the drying cover plate 762 is detachably connected to the drying channel 761 via screws or snap-fit ​​structures, facilitating maintenance or cleaning.

[0441] In some embodiments, the drying air passage 760 extends from the second annular member 742 to the bottom edge of the outer cylinder 710, and forms a vent 711 at the bottom of the outer cylinder 710. The vent 711 is used to assemble with the drying device 770. Specifically, the vent 711 protrudes axially from the bottom surface of the outer cylinder 710, and the vent 711 is used to communicate with the drying conveying air duct 771 of the drying device 770. The drying conveying air duct 771 is installed with the air outlet 773 of the drying device 770. The drying airflow is introduced into the drying conveying air duct 771 from the air outlet 773, and then conveyed to the vent 711 to enter the drying air passage 760.

[0442] In some embodiments, the device further includes: a humidity sensor and / or a temperature sensor, or a temperature and humidity sensor, to detect the environment inside the drum and thus determine the drying status of the clothes. For example, the humidity sensor monitors the amount of water vapor evaporating from the clothes to determine the drying progress, and automatically adjusts the drying airflow and heating temperature based on the humidity data to avoid over-drying or under-drying; for example, the temperature sensor ensures that the hot air temperature remains stable within a set range, effectively improving the clothes care effect, and can precisely control the temperature according to different drying stages; or, for example, the humidity sensor and temperature sensor can work together, or a temperature and humidity sensor can be used, to simultaneously monitor the temperature and humidity inside the drum during the drying process.

[0443] In some embodiments, the gas-liquid conveying component 750 is provided with at least one set of ventilation holes 753 on the surface of the inner cylinder 720 facing the bottom of the cylinder, for directional conveying of drying airflow.

[0444] The shape of the gas-liquid conveying component 750 is adapted to the bottom of the inner cylinder 720. In this embodiment, the gas-liquid conveying component 750 is disc-shaped; different shapes of gas-liquid conveying components 750 can be designed as needed.

[0445] Specifically, the gas-liquid conveying component 750 has at least one chamber 752 inside; a fluid passage 743 communicates with at least one chamber 752; the chamber 752 is used to form a transition space for the drying airflow; in some embodiments, a fluid passage 743 is formed inside the sealing ring assembly 740, the gas-liquid conveying component 750 forms a chamber 752, the fluid passage 743 is connected to the chamber 752, and the chamber 752 is connected to at least one set of ventilation holes 753; after the drying airflow enters the chamber 752 through the fluid passage 743, the drying airflow is directly conveyed along the axial direction of the inner cylinder 720 through the ventilation holes 753 to form an axial through-flow path, which can directly penetrate the clothing layer from the axial direction and improve the drying efficiency.

[0446] It should be noted that multiple fluid passages 743 can be formed within the sealing ring assembly 740, corresponding to multiple chambers 752 formed within the gas-liquid conveying component 750, and each fluid passage 743 is connected to at least one chamber 752.

[0447] Furthermore, the arrangement of the ventilation holes 753 matches the arrangement of the drainage holes 721 at the bottom of the inner cylinder 720 to ensure the conveying rate of the drying airflow.

[0448] In some embodiments, each set of ventilation holes 753 has at least two air outlet directions to deliver the drying airflow to different areas inside the inner cylinder 720, thereby further expanding the coverage of the drying airflow and accelerating the drying rate.

[0449] Furthermore, the air outlet direction of each set of ventilation holes 753 is adjustable, realizing dynamic control of the drying airflow direction, further realizing refined management of the drying mode, and dynamically adjusting the drying airflow delivery strategy according to the drying stage, clothing type, etc.

[0450] In some embodiments, each set of ventilation holes 753 includes at least two different apertures, which can form different drying air volumes.

[0451] Furthermore, the diameter of the ventilation hole 753 is adjustable, which further enables precise control of the airflow during drying to adapt to different drying stages.

[0452] In some embodiments, the tripod 730 forms a positioning structure for limiting the position of the gas-liquid transport member 750; when the gas-liquid transport member 750 is assembled with the tripod 730, the ventilation hole 753 is aligned with the drain hole 721.

[0453] Furthermore, the ventilation hole 753 protrudes from the surface of the gas-liquid conveying component 750 to mate with the drain hole 721. Specifically, when the gas-liquid conveying component 750 and the tripod 730 are installed, the ventilation hole 753 can extend into the drain hole 721 to connect with the internal environment of the inner drum 720, so that the drying airflow can enter the inner drum 720 more quickly and smoothly, improving the drying efficiency of clothes.

[0454] In some embodiments, a damper is provided at the ventilation hole 753 to open or block the flow path of the drying airflow, thereby achieving dynamic and precise control of the flow path of the drying airflow.

[0455] In some embodiments, the inner wall of the inner cylinder is provided with lifting ribs 722, and the gas-liquid conveying component 750 is connected to the lifting ribs 722 to introduce drying airflow through the lifting ribs 722; further, the gas-liquid conveying component 750 includes at least one conveying pipe 751, and at least one of the conveying pipes 751 extends into the interior of the lifting ribs 722 to introduce drying airflow into the cylinder through the lifting ribs 722.

[0456] Furthermore, the number of conveying pipes 751 matches the number of lifting ribs 722, and each conveying pipe 751 extends into a corresponding lifting rib 722. Furthermore, each lifting rib 722 has a plurality of through holes 7221 for allowing drying airflow to pass through.

[0457] This embodiment of the invention also provides a garment care device 1, including the cylindrical body of the garment care device 1 as described above. This embodiment not only efficiently and reliably completes the rotary dynamic sealing function, but also integrates a continuous closed fluid passage 743 between the mutually fitting first annular member 741 and second annular member 742, thus integrating both rotary sealing and fluid delivery functions during rotation, thereby enhancing the functional diversity of the garment care device 1 and optimizing the user experience.

[0458] This utility model embodiment also provides a drying method for a garment care device, combined with Figure 23 As shown, the garment care device described above is controlled to perform the following steps:

[0459] S71. Receive a clothes drying command; in some embodiments, the clothes drying command is triggered when the clothes care device enters the drying stage; in other embodiments, the clothes drying command can be manually input by the user.

[0460] S72. Control the gas-liquid conveying component to deliver drying airflow into the inner cylinder.

[0461] The drying airflow from the fluid passage is redirected by the gas-liquid conveying component and transported axially into the inner drum, forming an axially penetrating airflow path. This effectively accelerates the contact and replacement efficiency between the humid air and the dry drying airflow inside the drum, significantly speeding up the drying of clothes and shortening the drying time. The axially introduced drying airflow, combined with the rotation of the inner drum, can better guide the airflow to form a more uniform flow field inside the drum. On the other hand, as the clothes tumble during the rotation of the inner drum, the drying airflow can more easily penetrate the stacked clothes, reducing dead airflow angles and ensuring more uniform drying of clothes.

[0462] In some implementations, combined Figure 24a As shown, it also includes the following steps:

[0463] S73. When the garment care device enters the drying stage, the condition of the garments inside the inner drum is obtained; wherein, the condition of the garments includes the weight of the garments and the distribution of the garments; in some optional embodiments, the distribution of the garments inside the washing drum can be collected by an infrared sensor or an image sensor; in other embodiments, the weight of the garments is obtained by a weight sensor, thereby assessing the degree of garment accumulation.

[0464] S74. Adjust the working mode of the gas-liquid conveying component according to the condition of the clothing.

[0465] In some alternative implementations, combined with Figure 24b As shown, the steps for adjusting the working mode of the gas-liquid conveying component according to the condition of the clothing include:

[0466] S741. Obtain the quantity and / or weight of the clothing inside the inner drum;

[0467] S742. Adjust the conveying power of the gas-liquid conveying component according to the quantity and / or weight of the clothing.

[0468] In some alternative implementations, the specific steps include:

[0469] Determine whether the weight of the clothing matches a preset weight threshold; wherein, each preset weight threshold corresponds to a different preset transmission power;

[0470] If the weight of the clothing matches the preset weight threshold, then the preset conveying power corresponding to the preset weight threshold is obtained as the conveying power of the gas-liquid conveying component.

[0471] For example, when the weight of the clothes is less than the first preset weight threshold (e.g., less than 2kg), it is determined that the weight of the clothes is too light. At this time, the conveying power of the gas-liquid conveying component is adjusted to a lower level to achieve gentle drying and avoid damage to thin clothes.

[0472] When the weight of the clothes is greater than or equal to the first preset weight threshold and less than the second preset weight threshold (for example, greater than or equal to 2kg and less than 4kg), the weight of the clothes is determined to be moderate. At this time, the conveying power of the gas-liquid conveying component is adjusted to the medium level to achieve a high-efficiency and energy-saving drying effect.

[0473] When the weight of the clothes is greater than or equal to the second preset weight threshold (e.g., greater than or equal to 4kg), it is determined that the weight of the clothes is too heavy. At this time, the conveying power of the gas-liquid conveying component is adjusted to a higher level to achieve rapid drying and improve drying efficiency.

[0474] In some alternative implementations, the steps include:

[0475] By adjusting the rotation mode of the inner cylinder to dynamically change the air outlet direction of the gas-liquid conveying component, the drying airflow inside the inner cylinder is altered.

[0476] Example 8

[0477] Currently, some washing machines incorporate steam vents to achieve functions such as high-temperature sterilization, high-temperature humidification, or air washing using high-temperature steam. The design of these steam vents directly impacts garment care, cleaning efficiency, and energy consumption. In existing technologies, steam vents are typically installed in fixed locations such as the side wall, bottom, or top of the outer drum, connected to a steam generator via a fixed pipe. However, fixed steam vents provide only one direction of steam, potentially leaving areas with piled-up clothes without steam contact, resulting in uneven steam coverage and blind spots in garment care. Furthermore, to ensure all clothes in the drum are exposed to steam, fixed steam vents require extended contact time or increased steam volume, leading to increased energy consumption.

[0478] Therefore, this embodiment of the invention also provides a cylindrical body for a garment care device 1, combined with... Figures 1-12 , Figures 25-26 As shown, it includes:

[0479] Inner cylinder 820; outer cylinder 810;

[0480] Tripod 830 is fixedly connected to the bottom of the inner cylinder 820 to transmit rotational driving force to the inner cylinder 820; and the end of the tripod 830 extends axially along the inner cylinder 820 and passes through the outer cylinder 810 to form a rotation shaft 831.

[0481] The sealing ring assembly 840 includes a first annular member 841 and a second annular member 842 whose end faces are tightly fitted together. The first annular member 841 is fixed to the rotating shaft 831, and the second annular member 842 is installed on the outer cylinder 810. When the first annular member 841 rotates with the rotating shaft 831, it can abut against the second annular member 842 to form a dynamic seal at the end of the rotating shaft 831. At least one continuously closed fluid passage 843 is formed between the first annular member 841 and the second annular member 842 within the sealing ring assembly 840 to connect the gas environment inside and outside the cylinder when the end of the rotating shaft 831 is sealed, i.e., to supply gas to the inside / outside of the outer cylinder 810 during the rotation of the inner cylinder 820.

[0482] A steam passage 860 is installed with the second annular member 842, and one end of the steam passage 860 is connected to at least one of the fluid passages 843, and the other end is connected to the steam generator 870 of the garment care device 1, for supplying steam to the fluid passage 843.

[0483] A gas-liquid conveying component 850 is installed with the first annular component 841; and the gas-liquid conveying component 850 is connected to the fluid passage 843 and the inner cylinder 820 respectively to form a steam guiding structure.

[0484] When the garment care device 1 is in steam washing mode, the gas-liquid conveying component 850 connects the internal environment of the cylinder and the steam passage 860 to introduce steam into the cylinder.

[0485] This embodiment not only efficiently and reliably completes the rotational dynamic sealing function, but also integrates a continuous closed fluid passage 843 between the mutually fitting first annular member 841 and second annular member 842, thus integrating both rotational sealing and fluid delivery functions during rotation. This enhances the functional diversity of the garment care device 1 and optimizes the user experience. The fluid passage 843 is embedded inside the sealing ring assembly 840, avoiding excessive additional space occupation and minimizing space usage.

[0486] The assembly structure, which fixes the first annular component 841 to the rotating shaft and the second annular component 842 to the outer cylinder 810, provides a stable sealing pressure between the first annular component 841 and the second annular component 842 and a stable pressure boundary for the fluid passage 843. On the other hand, it effectively simplifies the assembly method of the sealing ring assembly 840, making the axial structure more compact.

[0487] The gas-liquid conveying component 850 redirects the steam from the fluid passage 843 and axially transports it into the inner cylinder 820, forming an axially penetrating steam flow path. This expands the steam coverage area, facilitating the use of high-temperature steam for garment care (including disinfection, sterilization, cleaning, and wrinkle removal). Furthermore, the rotation of the inner cylinder 820 optimizes the steam flow path, creating convection between the axially flowing steam and the dynamically tumbling garments. This allows the steam to penetrate deep into garment folds and fiber gaps, while simultaneously ensuring a more uniform steam temperature distribution within the cylinder, preventing steam concentration in any one area, improving utilization, and optimizing garment care results. The gas-liquid conveying component 850 is made of high-temperature resistant and corrosion-resistant materials.

[0488] In some embodiments, the steam passage 860 is embedded in the bottom of the outer cylinder 810.

[0489] In some alternative embodiments, the steam passage 860 includes a steam pipe embedded in the bottom of the outer cylinder 810; integrating the steam pipe into the wall thickness of the bottom of the outer cylinder 810 significantly saves axial and radial space, maximizes space utilization, and makes the structure compact; furthermore, the steam pipe is hidden inside the bottom of the outer cylinder 810, completely avoiding the risk of interference between exposed pipes and the rotating shaft 831, and improving operational reliability.

[0490] In some alternative embodiments, the steam passage 860 includes a steam channel 861 formed at the bottom of the outer cylinder 810 and a steam cover 862 covering the steam channel 861; this simplifies the manufacturing process and reduces manufacturing costs. Specifically, the steam channel 861 is integrally formed with the outer cylinder 810, possessing good structural strength and contributing to structural stability. Furthermore, the steam cover 862 is detachably connected to the steam channel 861 via screws or snap-fit ​​structures, which facilitates maintenance or cleaning.

[0491] In some embodiments, the steam passage 860 extends from the second annular member 842 to the bottom edge of the outer cylinder 810, and a steam inlet 811 is formed at the bottom of the outer cylinder 810. The steam inlet 811 is used to connect with the steam generator 870 of the garment care device 1. Specifically, the steam inlet 811 protrudes axially from the bottom surface of the outer cylinder 810, and the steam inlet 811 is used to communicate with the steam delivery pipe 871851 of the steam generator 870; the steam generator 870 inputs steam into the steam delivery pipe 871851, and then the steam enters the steam passage 860 through the steam inlet 811.

[0492] In some embodiments, the system further includes a temperature sensor for real-time monitoring of steam temperature to facilitate timely detection of steam status.

[0493] In some embodiments, the gas-liquid conveying component 850 is provided with at least one set of steam ports 853 on the surface facing the bottom of the inner cylinder 820 for directional conveying of steam.

[0494] The shape of the gas-liquid conveying component 850 is adapted to the bottom of the inner cylinder 820. In this embodiment, the gas-liquid conveying component 850 is disc-shaped; different shapes of gas-liquid conveying components 850 can be designed as needed.

[0495] Specifically, the gas-liquid conveying component 850 has at least one chamber 852 inside; a fluid passage 843 communicates with at least one chamber 852; the chamber 852 is used to form a steam transition space; in some embodiments, a fluid passage 843 is formed inside the sealing ring assembly 840, the gas-liquid conveying component 850 forms a chamber 852, the fluid passage 843 is connected to the chamber 852, and the chamber 852 is connected to at least one set of steam ports 853; after the steam enters the chamber 852 through the fluid passage 843, the steam is directly conveyed along the axial direction of the inner cylinder 820 through the steam ports 853, so that the steam is evenly diffused along the rotation direction of the inner cylinder 820, covering all areas of the inner garment and avoiding local steam shortage.

[0496] It should be noted that multiple fluid passages 843 can be formed within the sealing ring assembly 840, corresponding to multiple chambers 852 formed within the gas-liquid conveying component 850, and each fluid passage 843 is connected to at least one chamber 852.

[0497] In some embodiments, each group of steam vents 853 has at least two different output directions to deliver steam to different areas inside the inner drum 820, further expanding the effect of steam and improving the garment care effect.

[0498] Furthermore, the output direction of each steam port 853 is adjustable, enabling dynamic control of the steam direction and further refining the management of steam care. The steam delivery strategy can be dynamically adjusted according to the type of clothing, washing stage, etc.

[0499] In some embodiments, each group of steam vents 853 includes at least two different apertures to create different steam delivery volumes, adapting to various garment care scenarios. Furthermore, the diameter of the steam vents 853 is adjustable, further enabling precise control of the steam delivery volume.

[0500] In some embodiments, the steam port 853 has an aperture of 1-3 mm, and the steam can be sprayed out in a fine mist, reducing the impact on clothing and optimizing the clothing care effect.

[0501] In some embodiments, the arrangement of the steam inlets 853 in each group matches the arrangement of the drain holes 821 at the bottom of the inner drum 820 to ensure the steam delivery rate so that it reaches the clothes in the inner drum 820 directly.

[0502] In some embodiments, the tripod 830 forms a positioning structure for limiting the position of the gas-liquid conveying member 850; when the gas-liquid conveying member 850 is assembled with the tripod 830, the steam port 853 is aligned with the drain hole 821.

[0503] Furthermore, the steam port 853 protrudes from the surface of the gas-liquid conveying component 850 to mate with the drain hole 821. Specifically, when the gas-liquid conveying component 850 and the tripod 830 are installed, the steam port 853 can extend into the drain hole 821 to connect with the internal environment of the inner cylinder 820, so that steam can enter the inner cylinder 820 more quickly and smoothly.

[0504] In some embodiments, a switch structure is provided at the steam port 853 to open or block the steam flow path, thereby achieving dynamic and precise control of the steam flow path.

[0505] In some embodiments, the inner wall of the inner cylinder 820 is provided with a lifting rib 822, and the gas-liquid conveying component 850 is connected to the lifting rib 822 to convey steam through the lifting rib 822; further, the gas-liquid conveying component 850 includes at least one conveying pipe 851, and at least one of the conveying pipes 851 extends into the interior of the lifting rib 822 to convey steam.

[0506] Furthermore, the number of conveying pipes 851 matches the number of lifting ribs 822, and each conveying pipe 851 extends into a corresponding lifting rib 822.

[0507] Furthermore, the lifting rib 822 has a plurality of through holes 8221 for allowing steam to pass through.

This embodiment not only efficiently and reliably completes the rotary dynamic sealing function, but also integrates a continuous closed fluid passage 843 between the mutually fitting first annular member 841 and second annular member 842, thus integrating both rotary sealing and fluid delivery functions during rotation, thereby enhancing the functional diversity of the garment care device 1 and optimizing the user experience.
