Description

Technical Field

[0001] This invention relates to the field of fabric processing equipment technology, and in particular to a fabric processing device and control method. Background Technology

[0002] In the field of fabric treatment equipment, such as mini washing machines, there are significant shortcomings in fabric care functions. Traditional mini washing machines mainly rely on mechanical agitation of water flow or drum rotation to achieve cleaning, while the application of steam care functions is relatively limited. Existing washing machines with steam functions typically use a fixed inner drum structure, with a single steam introduction method, making it impossible to achieve differentiated steam care based on differences in fabric material, thickness, and other factors. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that in the prior art, washing machines with steam function usually use a fixed inner drum structure and a single steam introduction method, which cannot achieve differentiated steam care according to differences in fabric material, thickness and other factors. Therefore, a fabric treatment device and control method are provided.

[0004] This invention aims to provide a fabric treatment apparatus, comprising:

[0005] outer cylinder;

[0006] An inner cylinder, which is rotatably disposed within the outer cylinder;

[0007] The lifting rib is disposed on the circumferential wall of the inner cylinder. A first through hole communicating with the outer cylinder is opened only in the area covered by the lifting rib on the circumferential wall of the inner cylinder. A second through hole communicating with the first through hole is opened on the side wall of the lifting rib.

[0008] A sealing assembly, the sealing assembly including a sealing baffle, the sealing baffle being configured to have a first position state blocking the first through hole and a second position state opening the first through hole, the sealing baffle being in the first position state blocking steam outside the lifting rib from flowing through the second through hole, and the sealing baffle being in the second position state allowing steam outside the lifting rib to flow through the second through hole;

[0009] A steam generator is disposed inside the outer cylinder.

[0010] In some embodiments, the steam generator includes a heater disposed between the outer cylinder and the inner cylinder.

[0011] In some embodiments, a temperature sensing element is provided inside the inner cylinder, and the heater is configured to controllably reduce the heating power when the temperature detected by the temperature sensing element exceeds a first preset temperature, and to controllably increase the heating power when the temperature detected by the temperature sensing element is lower than a second preset temperature.

[0012] In some embodiments, the lifting rib has a first sidewall, a third sidewall, a second sidewall, and a fourth sidewall connected in sequence;

[0013] The first through hole is formed on the first side wall and / or the second side wall, and the sealing baffle is movably disposed on the inner wall surface of the first side wall and / or the second side wall. The first position state is when the sealing baffle moves to the first side wall and / or the second side wall to block the second through hole, and the second position state is when the sealing baffle moves to the first side wall and / or the second side wall to open the second through hole.

[0014] The lifting rib includes a driving component, the output end of which is connected to the sealing baffle for driving the sealing baffle to move to the first position state or the second position state.

[0015] In some embodiments, a groove is provided on the inner side of the lifting rib where the first through hole is formed, the first through hole is located in the groove, a first sealing ring is provided on one side plate of the sealing baffle, the sealing baffle is in a first position state, the first sealing ring is sealed to the groove opening, and the second through hole is blocked by the sealing baffle.

[0016] In some embodiments, the inner cylinder and the outer cylinder are arranged vertically, and the heater is located between the bottom wall of the outer cylinder and the bottom wall of the inner cylinder.

[0017] In some embodiments, the inner cylinder and the outer cylinder are arranged horizontally, and the heater is located between the bottom of the outer cylinder's circumferential wall and the inner cylinder's circumferential wall.

[0018] In some embodiments, a control method for the above-described fabric processing equipment is provided, wherein multiple lifting ribs are provided, and the control method includes:

[0019] According to the set steam care mode, control the sealing baffles on the multiple lifting ribs to move to the first position state or the second position state to change the number of the second through holes communicating with the outside of the lifting ribs;

[0020] The fabric processing equipment is controlled to start the water inlet program, and water is introduced between the outer cylinder and the inner cylinder until the preset water level is reached and then the water inlet is stopped;

[0021] The steam generator is started, and steam is generated and enters the inner cylinder through the first through hole and the second through hole.

[0022] In some embodiments, the control method includes: after controlling the steam generator to start, acquiring the temperature inside the inner cylinder; when the temperature exceeds a first preset temperature, controlling the heater power of the steam generator to decrease; and when the temperature is lower than a second preset temperature, controlling the heater power of the steam generator to increase.

[0023] In some embodiments, the control method includes: acquiring the material parameters of the fabric inside the inner cylinder, and determining the steam care mode based on the material parameters of the fabric.

[0024] In some embodiments, the control method includes determining the preset water level according to the steam care mode.

[0025] The solution provided by this invention has the following advantages compared with the prior art:

[0026] By creating a first through hole on the inner cylinder's circumferential wall, connecting it to the outer cylinder only within the area covered by the lifting ribs, the opening and closing of this first through hole can be controlled by manipulating the lifting ribs. This allows users to select either a non-perforated or perforated inner cylinder as needed. Combined with the structural design of the lifting ribs, an opening and closing sealing baffle allows them to switch between non-perforated and perforated lifting ribs. When the sealing baffle blocks and closes the second through hole, the lifting rib is non-perforated, and the first through hole on the inner cylinder is closed, resulting in a non-perforated inner cylinder. When the sealing baffle opens the second through hole, the lifting rib becomes perforated, and the first and second through holes on the inner cylinder connect, resulting in a perforated inner cylinder. For a non-perforated inner cylinder structure, the steam provided by the steam generator can enter the inner cylinder through the first through hole, the lifting rib, and then through the second through hole, thus distributing the steam more evenly inside the inner cylinder. This avoids the problem of uneven steam distribution caused by the perforated structure on the traditional inner cylinder. By manipulating the lifting rib, the fabric treatment equipment can control the steam to enter the inner cylinder through the first through hole in a specific part of the cylinder's circumferential wall. The inlet is unique, and the probability of it being blocked is small. This ensures that the steam is evenly distributed in the inner cylinder. The number of second through holes connected to the outside of the lifting rib can also be controlled by manipulating the lifting rib, thereby controlling the amount of steam entering. This allows for differentiated steam care of fabrics based on different factors such as fabric type and material. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0042] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] Existing washing machines with steam functions typically use a fixed inner drum structure, resulting in a single steam introduction method that cannot provide differentiated steam care based on fabric material, thickness, and other factors. Current technologies often involve spraying a small amount of steam into the drum opening during washing or drying to remove wrinkles or provide mild sterilization. However, this method lacks adjustable care intensity. Traditional washing machine drums usually have drain holes, which can easily cause steam leakage during the steam care process, affecting efficiency and resulting in uneven steam distribution and limited care effects.

[0044] Based on this, the following embodiments are proposed.

[0045] Example 1:

[0046] like Figure 1 ,4 As shown in Figure 8, this embodiment provides a fabric processing device, including: an outer cylinder 3;

[0047] The inner cylinder 6 is rotatably disposed within the outer cylinder 3; a lifting rib 1 is disposed on the circumferential wall of the inner cylinder 6, and a first through hole 201 communicating with the outer cylinder 3 is formed only in the area covered by the lifting rib 1 on the circumferential wall of the inner cylinder 6; a second through hole 107 communicating with the first through hole 201 is formed on the side wall of the lifting rib 1; a sealing assembly includes a sealing baffle 2, which is configured to have a first position state blocking the second through hole 107 and a second position state opening the second through hole 107. In the first position state, the sealing baffle 2 blocks the flow of steam outside the lifting rib 1 through the second through hole 107; in the second position state, the sealing baffle 2 allows the flow of steam outside the lifting rib 1 through the second through hole 107; and a steam generator is disposed inside the outer cylinder 3. The steam generator is used to provide steam to the inner cylinder 6.

[0048] In this embodiment, by opening a first through hole 201 on the circumferential wall of the inner cylinder 6 in the area covered by the lifting rib 1, which communicates with the outer cylinder 3, the opening and closing of the first through hole 201 on the inner cylinder 6 can be achieved by controlling the lifting rib. Thus, the user can choose a perforated inner cylinder or a non-perforated inner cylinder as needed. Based on the structural design of the lifting rib 1, the sealing baffle 2 is opened and closed to allow the lifting rib 1 to switch between a non-perforated lifting rib and a perforated lifting rib. When the sealing baffle 2 blocks the second through hole 107 and closes the second through hole 107, i.e., the sealing baffle 2 is in the first position, the lifting rib 1 is a non-perforated lifting rib, and the first through hole 201 on the inner cylinder 6 is closed by the lifting rib, thus the inner cylinder 6 is a non-perforated inner cylinder. When the sealing baffle 2 opens the second through hole 107, i.e., the sealing baffle 2 is in the second position, the lifting rib 1 is a perforated lifting rib, and the first through hole 201 on the inner cylinder 6 is connected to the second through hole 107, thus the inner cylinder 6 is a perforated inner cylinder.

[0049] For a non-perforated inner cylinder structure, steam supplied by the steam generator can enter the inner cylinder through the first through-hole 201, the lifting rib 1, and then through the second through-hole 107, thus achieving a more uniform distribution inside the inner cylinder 6. This avoids the uneven steam distribution problem caused by the perforated structure on traditional inner cylinders. For example, in the process of steam entering the inner cylinder in a traditional inner cylinder, steam usually enters the inner cylinder first through the through-holes on the bottom wall of the inner cylinder. However, some of the through-holes on the bottom wall of the cylinder are blocked by the fabric inside the cylinder, resulting in uneven air intake and distribution. In contrast, the fabric treatment device proposed in this embodiment can control the steam to enter the inner cylinder 6 through a specific part of the first through-hole 201 on the circumferential wall of the inner cylinder 6 by manipulating the lifting ribs. The entry point is unique, and the probability of being blocked is small. This ensures that the steam is evenly distributed in the inner cylinder. Furthermore, the number of second through-holes 107 connected to the outside of the lifting rib 1 can be controlled by manipulating the lifting ribs, thereby controlling the amount of steam entering and achieving differentiated steam treatment of fabrics based on different factors such as fabric type and material.

[0050] In this embodiment, by setting multiple lifting ribs 1 and controlling the opening and closing of the sealing baffle 2 on the lifting rib 1, the user can adjust the opening or closing layout of the lifting ribs according to their needs to change the number of second through holes 107 communicating with the outside of the lifting rib 1. Alternatively, by setting a single lifting rib 1 and controlling the opening and closing angle of the sealing baffle on the lifting rib 1, the opening size of the passage communicating with the outside of the lifting rib 1 can be changed. This enables control of the steam flow rate into the inner drum 6, achieving targeted care for different fabrics. This results in improved care effect, extended fabric life, and satisfaction of diverse care needs. It solves the technical problem that existing washing machines cannot achieve differentiated steam care according to fabric type and care needs during the steam care process.

[0051] Optionally, such as Figure 2 , 3 As shown, in one implementation of this embodiment, the steam generator includes a heater 7, which is disposed between the outer cylinder 3 and the inner cylinder 6.

[0052] In this embodiment, the steam generator includes a heater 7. The heater 7 heats the water between the inner cylinder 6 and the outer cylinder 3, thereby generating steam between the inner cylinder 6 and the outer cylinder 3. The steam enters the inner cylinder 6 through the first through hole 201 and the second through hole 107 to steam care for the fabric.

[0053] Preferably, the inner cylinder 6 and the outer cylinder 3 are vertically arranged, and the heater 7 is located between the bottom wall of the outer cylinder 3 and the bottom wall of the inner cylinder 6. In the fabric processing equipment, the inner cylinder 6 and the outer cylinder 3 are vertically arranged, and the heater 7 is located between the bottom wall of the outer cylinder 3 and the bottom wall of the inner cylinder 6. By introducing water between the inner cylinder 6 and the outer cylinder 3 to a first preset water level, steam can be generated only at or below this first preset water level. The steam can directly enter the inner cylinder 6 through the first through hole 201 and the second through hole 107, ensuring safety and better preventing steam from turning into droplets.

[0054] Preferably, the inner cylinder 6 and the outer cylinder 3 are arranged horizontally, and the heater 7 is located between the bottom of the outer cylinder 3's circumferential wall and the inner cylinder 6's circumferential wall. In this fabric processing equipment, the inner cylinder 6 and the outer cylinder 3 are arranged horizontally, and the heater 7 is located between the bottom of the outer cylinder 3's circumferential wall and the inner cylinder 6's circumferential wall. By introducing water between the inner cylinder 6 and the outer cylinder 3 to a second preset water level, steam can be generated only at or below this second preset water level. The steam can directly enter the inner cylinder 6 through the first through hole 201 and the second through hole 107, ensuring safety and better preventing steam from converting into droplets.

[0055] like Figure 2 As shown, the first preset water level H1 shall not exceed the bottom position of the lifting rib 1, as follows. Figure 3 As shown, the second preset water level H2 does not exceed the bottom position of the lowest lifting rib 1. This prevents water from entering the inner cylinder 6 through the first through hole 201 and the second through hole 107 before it is converted into steam. The first preset water level H1 or the second preset water level H2 can be adjusted according to the steam treatment intensity. For example, if the steam treatment intensity is high, the first preset water level H1 or the second preset water level H2 can be set higher to provide sufficient water. If the steam treatment intensity is low, the first preset water level H1 or the second preset water level H2 can be set lower to avoid wasting water.

[0056] Optionally, in one implementation of this embodiment, a temperature sensing element is provided inside the inner cylinder 6, and the heater 7 is configured to controllably reduce the heating power when the temperature detected by the temperature sensing element exceeds a first preset temperature, and to controllably increase the heating power when the temperature detected by the temperature sensing element is lower than a second preset temperature.

[0057] In this embodiment, the temperature sensing element can be a temperature sensing bulb or a temperature sensor. Under the preset steam care intensity, the washing machine control board has a maximum temperature and a minimum temperature adapted to the steam care intensity, namely a first preset temperature and a second preset temperature. The first preset temperature and the second preset temperature constitute a temperature range. When the temperature sensing element detects that the temperature inside the inner drum 6 exceeds the first preset temperature, the control board receives the signal and controls the heater 7 to reduce the heating power to avoid damage to the fabric due to excessive steam. When the temperature sensing element detects that the temperature inside the inner drum 6 is lower than the second preset temperature, the control board receives the signal and controls the heater 7 to increase the heating power to avoid insufficient steam care for the fabric due to insufficient steam.

[0058] Preferably, a guide plate is provided on the bottom wall of the inner cylinder 6 so that the steam can flow along a specific path after entering the inner cylinder 6, thereby improving the steam utilization rate.

[0059] Optionally, such as Figure 4-8 In one implementation of this embodiment, a groove 106 is provided on the inner or outer side of the lifting rib 1 where the second through hole 107 is opened, the second through hole 107 is located in the groove 106, a first sealing ring 13 is provided on one side plate of the sealing baffle 2, the sealing baffle 2 is in a first position state, the first sealing ring 13 is sealed to the groove opening of the groove 106, and the second through hole 107 is blocked by the sealing baffle 2.

[0060] In this embodiment, the arrangement of the first sealing ring 13 and the groove 106 further enhances the sealing effect of the sealing baffle 2 on the second through hole 107, thereby further enhancing the blocking effect of the sealing baffle 2 on the second through hole 107 and the outside of the outer shell when the opening of the groove 106 is closed.

[0061] Optionally, such as Figure 4 , 5 In one implementation of this embodiment, the lifting rib 1 has a first sidewall 101, a third sidewall 103, a second sidewall 102 and a fourth sidewall 104 connected in sequence.

[0062] The second through hole 107 is formed on the first side wall 101 and / or the second side wall 102. The sealing baffle 2 is detachably installed on the outer wall surface of the first side wall 101 and / or the second side wall 102. The first position state is that the sealing baffle 2 is installed on the first side wall 101 and / or the second side wall 102 to block the second through hole 107. The second position state is that the sealing baffle 2 is removed from the first side wall 101 and / or the second side wall 102 to open the second through hole 107.

[0063] In this embodiment, the groove 106 is formed on the outer wall surface of the first sidewall 101 and / or the second sidewall 102. Taking the groove 106 located on the outer wall surface of the second sidewall 102 as an example, when the groove 106 is located on the outer wall surface of the second sidewall 102, the first position state is that the sealing baffle 2 is installed in the groove 106 of the first sidewall 101 and / or the second sidewall 102, and the sealing baffle 2 can be snapped onto the outside of the lifting rib 1, thereby facilitating manual operation of opening and closing of the sealing baffle 2 without the user needing to disassemble the lifting rib 1. The second position state is that the sealing baffle 2 is detached from the groove 106 of the first sidewall 101 and / or the second sidewall 102, and the groove 106 is opened. The second through hole 107 allows the user to use a perforated inner cylinder simply by removing the sealing baffle 2 from the lifting rib 1, opening the groove 106 and thus connecting the second through hole 107 to the outside of the lifting rib 1. This allows water inside the inner cylinder 6 to enter the lifting rib 1 and drain out through the opening and the drain hole on the inner cylinder 6, thus making the inner cylinder 6 a perforated inner cylinder. When the user prefers a non-perforated inner cylinder, the sealing baffle 2 can be snapped onto the lifting rib 1 to block the groove 106, closing it and preventing water from entering the lifting rib 1, making the inner cylinder 6 a non-perforated inner cylinder, which is more convenient to operate.

[0064] Optionally, such as Figure 1 , 2 As shown, in one implementation of this embodiment, a first snap-fit ​​structure 4 is provided on the sealing baffle 2, and a second snap-fit ​​structure 5 corresponding to the first snap-fit ​​structure is provided on the first sidewall 101 and / or the second sidewall 102. The first snap-fit ​​structure and the second snap-fit ​​structure 5 are detachably connected by snap-fit.

[0065] Furthermore, a first partition plate 16 is provided inside the cavity 105, which divides the cavity 105 into a first sub-cavity 1051 and a second sub-cavity 1052.

[0066] The second through hole 107 is disposed on the cavity wall of the first sub-cavity 1051, the first snap-fit ​​structure 4 is a snap hook, the second snap-fit ​​structure 5 is a snap groove, the snap groove is on the cavity wall of the second sub-cavity 1052, and the snap hook and the snap groove engage to achieve the sealing baffle 2 blocking the second through hole 107.

[0067] In this embodiment, the first snap-fit ​​structure 4 can be a hook, and the second snap-fit ​​structure 5 can be a slot. There are two hooks and two slots. The two hooks are fixedly connected to both ends of the sealing baffle 2, and the two slots are located on the second sidewall 102 at positions corresponding to the hooks. Therefore, when the user prefers to use the perforated inner cylinder, they first pry one side of the sealing baffle 2 outwards to separate the hooks and slots, removing the sealing baffle 2 from the lifting rib 1. The groove 106 is then opened, thereby opening the second through hole 107 and the lifting rib. The external connection allows water inside the inner cylinder 6 to enter the interior of the lifting rib 1 and then drain out through the opening and the drain hole on the inner cylinder 6. Even if the inner cylinder 6 is a perforated inner cylinder, if the user prefers to use a non-perforated inner cylinder, the hook is engaged with the corresponding slot, and the sealing baffle 2 is fixed on the lifting rib 1, thereby blocking the groove 106, closing the groove 106, and blocking the connection between the second through hole 107 and the outside of the lifting rib 1, so that water inside the inner cylinder 6 cannot enter the interior of the lifting rib 1. Even if the inner cylinder 6 is a non-perforated inner cylinder, the operation is more convenient.

[0068] In this embodiment, the first partition plate 16 divides the cavity 105 into multiple sub-cavities. This design facilitates the setting of the slot. For example, two first partition plates 16 are provided, one of which is close to the third side wall 103, and the other is close to the fourth side wall 104.

[0069] The sub-cavity includes a first sub-cavity 1051 and two second sub-cavities 1052;

[0070] A first sub-cavity 1051 is formed between two first partition plates 16, a second sub-cavity 1052 is formed between one first partition plate 16 and the third sidewall 103, and another second sub-cavity 1052 is formed between another first partition plate 16 and the fourth sidewall 104.

[0071] In this embodiment, the second through hole 107 is connected to the first sub-cavity 1051, and the slot is connected to the corresponding second sub-cavity 1052. When the sealing baffle 2 blocks or opens the second through hole 107, it simultaneously blocks or opens the slot. In this embodiment, the volume of the first sub-cavity 1051 is relatively large, and the volumes of the second sub-cavities 1052 on both sides are relatively small. No through holes are provided on the inner wall of the inner cylinder 6 at the location corresponding to the second sub-cavity 1052. Through holes are only provided on the inner wall of the inner cylinder 6 at the location corresponding to the first sub-cavity 1051. Therefore, there is no need to set additional sealing structures for the second sub-cavity 1052 and the slot.

[0072] Preferably, both the third sidewall 103 and the fourth sidewall 104 are provided with hand grooves 108. The hand grooves 108 facilitate the user to manually operate and pry open the end of the sealing baffle 2, thereby separating the hook from the groove.

[0073] Optionally, such as Figure 6-8 In one implementation of this embodiment, the lifting rib 1 has a first sidewall 101, a third sidewall 103, a second sidewall 102 and a fourth sidewall 104 connected in sequence.

[0074] The second through hole 107 is formed on the first side wall 101 and / or the second side wall 102. The sealing baffle 2 is movably disposed on the inner wall surface of the first side wall 101 and / or the second side wall 102. The first position state is when the sealing baffle 2 moves to the first side wall 101 and / or the second side wall 102 to block the second through hole 107. The second position state is when the sealing baffle 2 moves to the first side wall 101 and / or the second side wall 102 to open the second through hole 107.

[0075] The lifting rib 1 includes a driving component, the output end of which is connected to the sealing baffle 2 for driving the sealing baffle 2 to move to the first position state or the second position state.

[0076] In this embodiment, the groove 106 is formed on the inner wall surface of the first sidewall 101 and / or the second sidewall 102. The description will take the example of the groove 106 being located on the inner wall surface of the first sidewall 101. Figure 4 As shown, when the groove 106 is located on the inner wall of the first side wall 101, the sealing baffle 2 is more suitable to be set inside the lifting rib 1, so that the drive assembly can drive the sealing baffle 2 to rotate and open and close the groove 106. The rotation of the sealing baffle 2 can be automatically controlled. Since the sealing baffle 2 is set inside the lifting rib 1, it will not occupy the space outside the lifting rib. When the user prefers to use a perforated inner cylinder, the drive assembly is controlled to drive the sealing baffle 2 to rotate and open the groove 106. When a non-perforated inner cylinder is required, the drive assembly is controlled to work and drive the sealing baffle 2 to rotate and close the groove 106.

[0077] Optionally, such as Figure 3-6 As shown, in one implementation of this embodiment, the lifting rib further includes a driving component. The output end of the driving component is connected to the sealing baffle 2 for driving the sealing baffle 2 to move to the first position state or the second position state.

[0078] Furthermore, one side of the sealing baffle 2 is rotatably disposed within the cavity 105, and the output end of the driving component is connected to one side of the sealing baffle 2 for driving the sealing baffle 2 to flip to the first position state or the second position state.

[0079] In this embodiment, the cooperation between the drive assembly and the sealing baffle 2 further solves the problem that the washing machine cannot automatically switch between a perforated inner drum and a non-perforated inner drum. By operating the drive assembly, the rotating end of the sealing baffle 2 is driven to rotate. Taking the groove 106 located on the inner wall surface of the first side wall 101 as an example, the sealing baffle 2 can be set to two rotation angles, such as... Figure 5 As shown, in the first rotation angle and first position state, the inclination angle of the sealing baffle 2 matches that of the first sidewall 101. Therefore, at the first rotation angle, the sealing baffle 2 fits against the groove 106, forming a complete seal around the groove 106. Figure 6 As shown, the second rotation angle is the second position state, and the sealing baffle 2 is adapted to the tilt angle of the second side wall 102. Thus, at the second rotation angle, the sealing baffle 2 is attached to the second side wall 102, forming a full opening of the groove 106. When the user prefers to use a perforated inner cylinder, the control drive assembly drives the sealing baffle 2 to rotate to the second rotation angle to open the groove 106. When a non-perforated inner cylinder is required, the control drive assembly works to drive the sealing baffle 2 to rotate to the first rotation angle to close the groove 106.

[0080] Optionally, such as Figure 3-6 As shown, in one implementation of this embodiment, a second partition plate 18 is provided in the cavity 105, and the second partition plate 18 divides the cavity 105 into a third sub-cavity 1054 and a fourth sub-cavity 1055.

[0081] The second through hole 107 is disposed on the cavity wall of the third sub-cavity 1054, the cavity wall of the fourth sub-cavity 1055 is a closed cavity wall, the drive assembly is sealed and installed in the fourth sub-cavity 1055, and the output end of the drive assembly extends through into the third sub-cavity 1054 and is connected to one side of the sealing baffle 2.

[0082] In this embodiment, the cavity 105 is divided into a third sub-cavity 1054 and a fourth sub-cavity 1055 by the second partition plate 18. The sealing baffle 2 is rotatably connected to the third sub-cavity 1054. The third sub-cavity 1054 is connected to the first through hole 201 on the circumferential wall of the inner cylinder 6. There are no holes at the position on the circumferential wall of the inner cylinder 6 corresponding to the fourth sub-cavity 1055, thus forming a relatively sealed fourth sub-cavity 1055 that does not allow water to pass through, and the drive component inside is waterproofed. The drive component is located inside the fourth sub-cavity 1055, and the sealing baffle 2 and the drive component are arranged in separate areas to facilitate waterproof protection of the drive component. When the user selects to use the perforated inner cylinder, the drive component is controlled to drive the sealing baffle 2 to rotate to the second rotation angle, opening the groove 106. Water flows through the second through hole 107 into the third sub-cavity 1054 and is discharged through the first through hole 201 on the circumferential wall of the inner cylinder 6, without passing through the fourth sub-cavity 1055.

[0083] Optionally, such as Figure 3-6 As shown, in one implementation of this embodiment, the drive assembly includes a drive motor 9, a transmission belt 11, and a rotating shaft 12. The output end of the drive motor 9 is connected to one end of the transmission belt 11, and the other end of the transmission belt 11 is connected to one end of the rotating shaft 12. The other end of the rotating shaft 12 extends through into the third sub-cavity 1054 and is connected to one side of the sealing baffle 2.

[0084] In this embodiment, the drive motor 9 operates, driving the transmission belt 11 to rotate. The rotation of the transmission belt 11 drives the rotating shaft 12 to rotate, which in turn drives the sealing baffle 2 to rotate. Thus, the drive motor 9 operates to drive the sealing baffle 2 to rotate. This embodiment proposes an automatically opening and closing lifting rib. The drive motor 9 drives the sealing baffle 2 to rotate within the lifting rib, thereby controlling the opening and closing of the lifting rib and realizing the automatic switching between a perforated inner drum and a non-perforated inner drum in the washing machine. This embodiment proposes a washing machine that can automatically switch between a perforated inner drum and a non-perforated inner drum, enabling automatic switching between the two modes according to user settings during washing and spin-drying.

[0085] The lifting rib proposed in this embodiment includes a main body, a drive motor 9, a transmission belt 11, a rotating shaft 12, and a sealing baffle 2. The main body can be understood as the lifting rib 1, which has a water inlet area and a sealing area. The water inlet area is the third sub-cavity 1054, and the sealing area is the fourth sub-cavity 1055. The sealing baffle 2 is located inside the water inlet area, and the drive motor 9 and transmission belt 11 are located inside the sealing area. When the sealing baffle 2 rotates to the side with water inlet holes in the water inlet area, all water inlet holes of the lifting rib are sealed; when the sealing baffle 2 rotates to the other side, all water inlet holes of the lifting rib are opened. By controlling the rotation angle of the sealing baffle 2, the opening degree of the internal passage of the lifting rib can be adjusted. The drive motor 9 can be a waterproof motor to further improve the safety of the drive motor 9.

[0086] The lifting rib is installed in the inner drum 6 of the washing machine. The sealing baffle 2 is driven to rotate by the drive motor 9, which can adjust the sealing and opening status and degree of the water inlet hole, and realize automatic control to switch between the inner drum with holes and the inner drum without holes.

[0087] like Figure 4 As shown, preferably, a second sealing ring 15 is provided at the point where the second partition plate 18 is penetrated by the rotating shaft 12, to further ensure the sealing performance of the sealing area and improve the safety of the drive motor 9.

[0088] In this embodiment, the power supply for the drive motor 9 can be directly supplied by battery, and the communication between the drive motor 9 and the main control board of the fabric processing equipment can be wireless communication.

[0089] Example 2

[0090] like Figure 1 , 9 As shown, this embodiment provides a control method for the fabric processing equipment in Embodiment 1, wherein multiple lifting ribs 1 are provided, and the control method includes:

[0091] According to the set steam care mode, control the sealing baffles 2 on the multiple lifting ribs to move to the first position state or the second position state to change the number of the second through holes 107 communicating with the outside of the lifting ribs;

[0092] The fabric processing equipment is controlled to start the water inlet program, and water is introduced between the outer cylinder 3 and the inner cylinder 6 until the preset water level is reached and then the water inlet is stopped.

[0093] The steam generator is started and steam is generated and enters the inner cylinder 6 through the first through hole 201 and the second through hole 107.

[0094] In this embodiment, when multiple lifting ribs 1 are provided, by controlling the opening and closing of the sealing baffle 2 on the lifting rib 1, the user can adjust the opening or closing layout of the lifting ribs according to their needs, thereby changing the number of second through holes 107 connected to the outside of the lifting rib 1, so as to achieve targeted care for different fabrics, thereby achieving the technical effects of improving care effect, extending fabric life and meeting diverse care needs. This solves the technical problem that existing washing machines cannot achieve differentiated steam care according to fabric type and care needs during the steam care process.

[0095] The following is an example illustrating the control steps of the control method: Three lifting ribs 1 are provided, the steam generator is a heater 7, the inner cylinder 6 and the outer cylinder 3 are arranged vertically, and the heater 7 is located between the bottom wall of the outer cylinder 3 and the bottom wall of the inner cylinder 6; the inner cylinder 6 and the outer cylinder 3 are arranged horizontally, and the heater 7 is located between the bottom of the circumferential wall of the outer cylinder 3 and the circumferential wall of the inner cylinder 6.

[0096] The inner cylinder 6 and the outer cylinder 3 are vertically arranged. Initially, the user selects the "gentle steam care" mode, and the controller of the fabric treatment equipment determines that the inner cylinder 6 is currently in a vertical state. The controller controls the sealing baffle 2 on one of the lifting ribs 1 to rotate, opening the second through hole 107 on the lifting rib 1. At this time, the system starts the water inlet program, introducing water between the outer cylinder 3 and the inner cylinder 6 until a preset water level is reached, then stopping the water inlet. The preset water level range includes a minimum water level and a maximum water level. The minimum water level is located above the heater 7 and is higher than the highest position of the heater 7, while the maximum water level is located below the lifting rib 1 and is lower than the minimum position of the lifting rib 1. After the water inlet stops, the heater 7 is controlled to operate, heating the water in the inner cylinder 6 and the outer cylinder 3 to generate high-temperature steam. The steam enters the interior of the inner cylinder 6 through the open second through hole 107 to care for the fabric. After the care time reaches the set value, the heater 7 stops operating. The fabric treatment equipment is then controlled to drain the water, completing the care process and ending the process. This care mode is suitable for delicate fabrics, such as wool and silk, to prevent excessive steam from entering the inner drum and damaging the fabric material.

[0097] If the user selects the "Powerful Steam Care" mode, the controller of the fabric treatment equipment determines that the inner cylinder 6 is currently in a vertical position. The controller controls the sealing baffles 2 on the three lifting ribs 1 to rotate, so that all the second through holes 107 on the three lifting ribs 1 are open. At this time, the system starts the water inlet program, introducing water between the outer cylinder 3 and the inner cylinder 6 until the preset water level is reached and then stops. The preset water level range has a minimum water level and a maximum water level. The minimum water level is located above the heater 7 and is higher than the highest position of the heater 7. The maximum water level is located below the lifting rib 1 and is lower than the minimum position of the lifting rib 1. After the water inlet stops, the heater 7 is controlled to work, heating the water in the inner cylinder 6 and the outer cylinder 3 to generate high-temperature steam. The steam enters the interior of the inner cylinder 6 through the open second through holes 107 to care for the fabric. After the care time reaches the set value, the heater 7 stops working. The fabric treatment equipment is then controlled to drain the water, and the care process ends. This care mode is suitable for fabrics such as pure cotton and outdoor clothing. A large amount of steam enters the inner drum, providing powerful care for the fabric and fully penetrating it to achieve the desired care effect, thus improving care efficiency.

[0098] The inner cylinder 6 and the outer cylinder 3 are arranged horizontally. Initially, the user selects the "gentle steam care" mode, and the controller of the fabric treatment equipment determines that the inner cylinder 6 is currently in a horizontal state. The controller controls the sealing baffle 2 on one of the lifting ribs 1 to rotate, so that the second through hole 107 on the lifting rib 1 is open, and can control the inner cylinder 6 to rotate so that the second through hole 107 in the open state is at the bottom position, so that steam can enter directly and the steam utilization rate is more efficient. At this time, the system starts the water inlet program, and water is introduced between the outer cylinder 3 and the inner cylinder 6 until the preset water level is reached and then water inlet stops. The preset water level range has a minimum water level and a maximum water level. The minimum water level is located above the heater 7 and is higher than the highest position of the heater 7. The maximum water level is located below the inner cylinder 6 and is lower than the minimum position of the inner cylinder 6. After the water inlet stops, the heater 7 is controlled to work, heating the water in the inner cylinder 6 and the outer cylinder 3 to generate high-temperature steam. The steam enters the interior of the inner cylinder 6 through the open second through hole 107 to care for the fabric.

[0099] If the user selects the "Powerful Steam Care" mode, the controller of the fabric treatment equipment determines that the inner cylinder 6 is currently in a horizontal position. The controller controls the sealing baffles 2 on the three lifting ribs 1 to rotate, so that all the second through holes 107 on the three lifting ribs 1 are open. At this time, the system starts the water inlet program, introducing water between the outer cylinder 3 and the inner cylinder 6 until the preset water level is reached and then stops. The preset water level range has a minimum water level and a maximum water level. The minimum water level is located above the heater 7 and is higher than the highest position of the heater 7. The maximum water level is located below the lifting rib 1 and is lower than the minimum position of the lifting rib 1. After the water inlet stops, the heater 7 is controlled to work, heating the water in the inner cylinder 6 and the outer cylinder 3 to generate high-temperature steam. The steam enters the interior of the inner cylinder 6 through the open second through holes 107 to care for the fabric. After the care time reaches the set value, the heater 7 stops working. The fabric treatment equipment is then controlled to drain water, and the care process ends.

[0100] Preferably, the inner cylinder 6 and the outer cylinder 3 are arranged horizontally. During the steam care mode, the inner cylinder 6 can be controlled to rotate at an ultra-low speed, which not only facilitates the uniform distribution of steam inside the inner cylinder 6, but also improves the contact efficiency between the fabric and the steam.

[0101] Optionally, such as Figure 10 As shown, in one implementation of this embodiment, after the steam generator is started, the temperature inside the inner cylinder 6 is obtained. When the temperature exceeds a first preset temperature, the power of the heater 7 of the steam generator is reduced. When the temperature is lower than a second preset temperature, the power of the heater 7 of the steam generator is increased.

[0102] In this embodiment, under a preset steam care intensity, the washing machine control board has a maximum temperature and a minimum temperature adapted to the steam care intensity, namely a first preset temperature and a second preset temperature. The first preset temperature and the second preset temperature constitute a temperature range. When the temperature sensor detects that the temperature inside the inner drum 6 exceeds the first preset temperature, the control board receives the signal and controls the heater 7 to reduce the heating power to avoid damage to the fabric due to excessive steam. When the temperature sensor detects that the temperature inside the inner drum 6 is lower than the second preset temperature, the control board receives the signal and controls the heater 7 to increase the heating power to avoid insufficient steam care for the fabric due to insufficient steam.

[0103] Optionally, in one implementation of this embodiment, such as Figure 11 As shown, the material parameters of the fabric inside the inner cylinder 6 are obtained, and the intensity of the steam treatment is determined based on the material parameters of the fabric.

[0104] In this embodiment, for example, if the fabric is a delicate material such as wool or silk, a low steam treatment intensity is selected to avoid damaging the fabric due to excessive steam intensity. If the fabric is pure cotton or outdoor clothing, a high steam treatment intensity is selected, allowing a large amount of steam to enter the inner drum for powerful fabric care, ensuring complete penetration and achieving the desired treatment effect, thus improving treatment efficiency. This achieves a fully automatic steam treatment mode.

[0105] Preferably, the preset water level is determined based on the intensity of the steam treatment. When the steam intensity is high, the preset water level is relatively high to provide sufficient water for the steam treatment; when the steam intensity is low, the preset water level is relatively low to avoid wasting water.

[0106] In summary, the ingenious design of the fabric processing equipment and control method lies in:

[0107] By creating a first through hole on the inner cylinder's circumferential wall, connecting it to the outer cylinder only within the area covered by the lifting ribs, the opening and closing of this first through hole can be controlled by manipulating the lifting ribs. This allows users to select either a non-perforated or perforated inner cylinder as needed. Combined with the structural design of the lifting ribs, an opening and closing sealing baffle allows them to switch between non-perforated and perforated lifting ribs. When the sealing baffle blocks and closes the second through hole, the lifting rib is non-perforated, and the first through hole on the inner cylinder is closed, resulting in a non-perforated inner cylinder. When the sealing baffle opens the second through hole, the lifting rib becomes perforated, and the first and second through holes on the inner cylinder connect, resulting in a perforated inner cylinder.

[0108] For a non-perforated inner cylinder structure, the steam provided by the steam generator can enter the inner cylinder through the first through hole, the lifting rib, and then through the second through hole, thus distributing the steam more evenly inside the inner cylinder. This avoids the problem of uneven steam distribution caused by the perforated structure on the traditional inner cylinder. By manipulating the lifting rib, the fabric treatment equipment can control the steam to enter the inner cylinder through the first through hole in a specific part of the cylinder's circumferential wall. The inlet is unique, and the probability of it being blocked is small. This ensures that the steam is evenly distributed in the inner cylinder. The number of second through holes connected to the outside of the lifting rib can also be controlled by manipulating the lifting rib, thereby controlling the amount of steam entering. This allows for differentiated steam care of fabrics based on different factors such as fabric type and material.

[0109] Furthermore, by setting multiple lifting ribs and controlling the opening and closing of the sealing baffles on the lifting ribs, users can adjust the opening or closing layout of the lifting ribs according to their needs, thereby changing the number of second through holes connected to the outside of the lifting ribs. This enables control of the steam flow rate into the inner drum, achieving targeted care for different fabrics. This results in improved care effects, extended fabric life, and the fulfillment of diverse care needs. It solves the technical problem that existing washing machines cannot achieve differentiated steam care based on fabric type and care needs during the steam care process.
