Description

Technical Field

[0001] This invention relates to the field of garment processing equipment, and specifically provides a garment processing device and a control method for the garment processing device. Background Technology

[0002] Existing washing machines typically remove stains from clothes by adding detergent. Detergent mainly removes stains through its chemical components. Whether the detergent can dissolve completely affects the washing effect. If the detergent cannot dissolve completely, it will remain on the clothes, causing damage.

[0003] In existing technologies, to accelerate the dissolution of detergent and the removal of stains from clothing, a gas generating device is usually introduced. The gas outlet of the gas generating device is located between the inner and outer drums. For example, the gas generating device is directly installed on the inner wall of the outer drum, and the bubbles generated by its gas outlet are directly emitted between the inner and outer drums. Alternatively, the gas generating device is located outside the outer drum, and the bubbles are introduced into the space between the inner and outer drums through a pipeline. Then, the bubbles enter the inner drum through the water permeable holes. However, the above-mentioned setups have limited effectiveness in dissolving detergent and removing stains from clothing.

[0004] To address the aforementioned issues, existing improvements have focused on modifying the gas generating device or related pipelines to increase the number of bubbles produced at the gas outlet or to generate microbubbles. While these improvements slightly enhance the removal of stains from clothing and the solubility of detergents, they have not yet achieved a level of effectiveness that satisfies users.

[0005] Accordingly, there is a need in the art for a new garment processing device and a control method for such a device to address the problem that existing washing machines have insufficient ability to remove stains from clothes and dissolve detergents. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problems, namely, to address the issue that existing washing machines have insufficient ability to remove stains from clothes and dissolve detergents.

[0007] In a first aspect, the present invention provides a garment processing device, characterized in that the garment processing device comprises: an inner drum having a vent hole; a venting element having an inlet and an outlet; a gas generating device having a gas outlet connected to the inlet; and a positioning device configured to position and release the inner drum; after the positioning device positions the inner drum, the gas generated by the gas generating device can enter the water storage area of ​​the inner drum through the outlet and the vent hole.

Under the drive of the second driving device, the second locking tongue can extend into the second groove and retract from the second groove.

[0010] In the preferred technical solution of the above-mentioned garment processing equipment, the motor driving the inner drum to rotate is a direct drive motor, and the driving body is the outer rotor of the direct drive motor; or a first pulley is sleeved on the transmission shaft that drives the inner drum to rotate, and a second pulley is sleeved on the output shaft of the motor, the first pulley and the second pulley are connected by a belt, and the driving body is the first pulley or the second pulley.

[0011] In the preferred embodiment of the above-mentioned clothing processing equipment, the inner wall of the inner cylinder is provided with lifting ribs, the lifting ribs and the inner wall form a cavity, and the insertion hole is located in the cavity.

[0012] In the preferred embodiment of the above-mentioned clothing processing equipment, the clothing processing equipment further includes a third driving device, which is connected to the venting component. Under the drive of the third driving device, the venting component can extend and retract on both the inner and outer sides of the venting hole. When the venting component extends into the inner side of the venting hole, the air outlet is located in the water storage area.

[0013] In the preferred embodiment of the above-mentioned garment processing equipment, the ventilation component is a rod body, and an airflow channel is formed inside the rod body along its axial direction. The air inlet and the air outlet are both connected to the airflow channel. The third driving device includes a motor and a transmission assembly, and the motor is connected to the rod body through the transmission assembly. Alternatively, the ventilation component is a bellows, and a pressure chamber is formed inside the wall of the bellows. A pressure port is provided on the wall of the bellows, and the pressure port is connected to the pressure chamber. The third driving device is a pneumatic device or a hydraulic device, and the outlet of the third driving device is connected to the pressure port. The end of the bellows away from the inner cylinder is connected to the gas outlet.

[0014] In the preferred embodiment of the above-mentioned garment processing equipment, the outer cylinder of the garment processing equipment is provided with a first mounting hole, and the garment processing equipment further includes a sealing element, the sealing element including a flexible cover, the bottom end of the flexible cover being open and the open end being sealed to the first mounting hole, the top end of the flexible cover being provided with a connecting hole, the venting element being provided through the connecting hole from the inside of the flexible cover, and the connecting hole being fixedly and sealed to the venting element, so that when the venting element extends into the inside of the venting hole, the flexible cover can form a seal with the venting hole; and / or the inner wall of the inner cylinder is provided with a lifting rib, the lifting rib being provided with a first through hole, the lifting rib and the inner wall forming a cavity, and the venting hole being located in the cavity.

[0015] In the preferred embodiment of the above-mentioned garment processing equipment, the air outlet is located between the inner drum and the outer drum of the garment processing equipment, and is correspondingly arranged with respect to the vent hole; and / or the garment processing equipment further includes a position sensing device, which is configured to be triggered when the inner drum rotates to a set position, so as to control the inner drum to stop rotating and to position the inner drum by the positioning device.

[0016] On the other hand, the present invention also provides a control method for a garment processing device, characterized in that the garment processing device includes: an inner drum with a vent hole; a venting element including an inlet and an outlet; a gas generating device including a gas outlet connected to the inlet; and a positioning device configured to position the inner drum; after the positioning device positions the inner drum, the gas generated by the gas generating device can enter the water storage area of ​​the inner drum through the outlet and the vent hole; the control method includes: controlling the inner drum to rotate during the washing process; controlling the inner drum to stop rotating when the inner drum rotates to a set position; controlling the positioning device to position and release the positioning of the inner drum; controlling the gas generating device to start; and controlling the positioning device to release the positioning of the inner drum after a preset time.

[0017] It is understood that the garment processing device of the present invention includes an inner tube, a venting component, a gas generating device, and a positioning device. The inner tube is provided with a vent hole, the venting component includes an air inlet and an air outlet, the gas generating device includes a gas outlet, the gas outlet is connected to the air inlet, and the positioning device is configured to be able to position and release the inner tube. After the positioning device positions the inner tube, the gas generated by the gas generating device can enter the water storage area of ​​the inner tube through the air outlet and the vent hole.

[0018] This application provides a vent hole on the inner drum, through which gas generated by the gas generator enters the water storage area of ​​the inner drum. This forms high-energy bubbles in the washing / rinsing water, which in turn create a large number of cavitation bubbles. The bursting of these billions of rigid cavitation bubbles generates a powerful impact force, effectively removing dirt from clothes, reducing detergent usage and residue, and significantly improving the stain removal and detergent dissolution effects.

[0019] The positioning device ensures that the gas generated by the gas generator enters the water storage area of ​​the inner drum. This is especially important when there is a lot of clothing in the inner drum, which results in a heavy load. After the inner drum stops rotating, the load distribution may become unbalanced. For example, if the load of clothing accumulates on the left or right side of the inner drum, it will continue to rotate under the influence of the load after the inner drum stops rotating. The present invention, through the positioning device, positions the inner drum after it stops rotating, preventing it from continuing to rotate. This ensures that the gas can enter the water storage area of ​​the inner drum from the gas outlet and through the vent. Attached Figure Description

Detailed Implementation

[0030] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.

[0031] It should be noted that in the description of this invention, terms such as "top" and "bottom," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "communication" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] like Figure 1 and Figure 2As shown, in order to address the problem that existing washing machines have insufficient effectiveness in removing stains from clothes and dissolving detergents, the clothing processing device of the present invention includes: an inner drum 1, a venting component 3, a gas generating device 4, and a positioning device 8. The inner drum 1 is provided with a vent hole 11; the venting component 3 includes an air inlet 31 and an air outlet 32; the gas generating device 4 includes a gas outlet 41, which is connected to the air inlet 31; the positioning device 8 is configured to position and release the inner drum 1; after the positioning device 8 positions the inner drum 1, the gas generated by the gas generating device 4 can enter the water storage area of ​​the inner drum 1 through the air outlet 32 ​​and the vent hole 11.

[0034] The gas generating device 4 can take various forms, such as an air pump, fan, or compressor. It can be installed on the inner wall of the garment processing equipment's casing or on the outer wall of the outer cylinder 2. Preferably, the gas generating device 4 is positioned above the liquid level in the water storage area, such as at the top of the inner wall of the casing, to prevent liquid from flowing back into the gas generating device 4. Alternatively, a water-resistant and breathable membrane can be installed at the air outlet 32 ​​of the ventilation component 3, allowing gas to exit through the outlet 32 ​​but preventing washing water from entering the ventilation component 3 through the outlet 32. The water-resistant and breathable membrane can be a polytetrafluoroethylene (PTFE) membrane or a PTFE membrane. In cases involving FE membranes, the placement of the gas generator 4 on the housing and outer cylinder 2 is not restricted. The gas outlet 41 of the gas generator 4 can be connected to the air inlet 31 of the ventilation component 3 via a connecting pipe 7, or it can be directly connected to the air inlet 31 of the ventilation component 3. The gas generator 4 can introduce gas in various ways. For example, when the gas generator 4 is located on the outer wall of the outer cylinder 2, its gas inlet can be connected to a hole on the housing of the garment processing equipment via a pipe; when the gas generator 4 is located on the inner wall of the housing, its gas inlet can be directly connected to a hole on the housing.

[0035] Furthermore, the specific forms of the clothing processing device of the present invention include various types, such as drum washing machines, pulsator washing machines, washer-dryer combos, etc., wherein the water storage area is the area of ​​the inner drum 1 used to hold washing water. When the clothing processing device is a drum washing machine, the water storage area is located on the radial bottom side of the inner drum 1, and when the clothing processing device is a pulsator washing machine, the water storage area is located on the axial bottom side of the inner drum 1.

[0036] Furthermore, it is understood that the vent 11 is different from the water permeable hole on the inner tube 1. Its diameter is much larger than that of the water permeable hole. The gas generated by the gas generating device 4 should be able to enter the water storage area of ​​the inner tube 1 through the vent 11. In addition, the vent 11 is not the clothing insertion port on the inner tube 1. The generated gas enters the water storage area of ​​the inner tube 1 through the vent 11. Compared with entering the water storage area of ​​the inner tube 1 through the clothing insertion port, there is no problem of interference when inserting or removing clothing.

[0037] Because the gas bubbles generated by the gas outlet of the existing gas generator are directly emitted between the inner and outer drums, the effect on dissolving detergent and removing stains from clothes is limited. The improvement solutions usually involve increasing the gas volume of the gas generator or improving the gas generator to produce microbubbles, but the final effect has not been significantly improved.

[0038] The applicant's research revealed that the probability of air bubbles entering the inner drum from the outer drum through the water-permeable holes is very small. Furthermore, experiments have shown that even very small microbubbles, rather than large ones, have difficulty effectively entering the inner drum. In other words, this application found that the main reason for the poor detergent dissolution and stain removal effect on clothing is not the quantity or size of the air bubbles produced, but rather that the water-permeable holes on the inner drum prevent air bubbles from effectively entering.

[0039] Based on the aforementioned problems not discovered by those skilled in the art, this application provides a vent hole 11 on the inner drum 1. The gas generated by the gas generating device 4 directly enters the water storage area of ​​the inner drum 1 through the vent hole 11, forming high-energy bubbles in the washing / rinsing water, and then forming a large number of cavitation bubbles in the water. Hundreds of billions of rigid cavitation bubbles burst, generating a powerful impact force, effectively removing dirt from clothes, reducing the amount of detergent used and residue, and significantly improving the stain removal and detergent dissolution effects.

[0040] Its working process includes: controlling the inner cylinder 1 to rotate to a position where gas can enter the water storage area of ​​the inner cylinder 1 through the air outlet 32 ​​and the air vent 11, for example, when the inner cylinder 1 rotates to a position where the air outlet 32 ​​is opposite to the air vent 11, controlling the inner cylinder 1 to stop rotating. At this time, the positioning device 8 is activated, thereby positioning the inner cylinder 1. After the positioning device 8 positions the inner cylinder 1, the gas generator 4 is activated, so that the gas enters the water storage area of ​​the inner cylinder 1 through the air outlet 32 ​​of the air vent 3 and the air vent 11, thereby completing efficient washing.

[0041] The positioning device 8 ensures that the gas generated by the gas generator 4 enters the water storage area of ​​the inner drum 1. Especially when there is a lot of clothing in the inner drum 1, the load is heavy. After the inner drum 1 stops rotating, the load distribution may be unbalanced. For example, when the load of clothing is concentrated on the left or right side wall of the inner drum 1, the inner drum 1 will still rotate under the action of the load after the inner drum 1 stops rotating. However, the present invention, through the positioning device 8, positions the inner drum 1 after the inner drum 1 stops rotating, preventing it from continuing to rotate. This ensures that the gas can enter the water storage area of ​​the inner drum 1 from the air outlet 32 ​​and through the vent hole 11. The side wall of the inner drum 1 includes a top side wall, a bottom side wall, a left side wall, and a right side wall. The bottom wall is the side closest to the ground after the clothing processing equipment is placed.

[0042] Specifically, there are various ways to position the inner cylinder 1, and the present invention will describe several possible implementation methods below.

[0043] In the first embodiment, the inner cylinder 1 is provided with an insertion hole 13. The positioning device 8 includes a first driving device 81 and a first locking tongue 82. The first driving device 81 is connected to the first locking tongue 82. Under the drive of the first driving device 81, the first locking tongue 82 can extend into the insertion hole 13 and retract from the insertion hole 13. Of course, the insertion hole 13 described above can also be replaced by a groove. For ease of explanation, the present invention will be described below using the insertion hole 13 as an example.

[0044] Specifically, such as Figure 3 As shown, the first locking tongue 82 can be a rod-shaped structure or a plate-shaped structure, etc. The present invention does not limit this structure. The first driving device 81 includes a motor, a cam, and a connecting rod. The motor can be fixed to the outer wall of the outer cylinder 2 or the inner wall of the housing by a bracket or other device. The output shaft of the motor is fixedly connected to the cam. The cam is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the first locking tongue 82. A second mounting hole 22 is provided on the side wall of the outer cylinder 2. The first locking tongue 82 passes through the second mounting hole 22. There is a movable gap between the first locking tongue 82 and the second mounting hole 22 so that the first locking tongue 82 can move through the second mounting hole 22. The second mounting hole 22 is movable and has a certain length to limit the first locking tongue 82, i.e., to limit its linear movement. The first locking tongue 82 is sealed to the second mounting hole 22. For example, the cover 9 is sealed to the periphery of the second mounting hole 22, and the top of the cover 9 is provided with a hole. After the first locking tongue 82 passes through the second mounting hole 22, it continues to pass through the hole of the cover 9 from the inside of the cover 9. The first locking tongue 82 is fixedly sealed to the hole of the cover 9. When the first locking tongue 82 is retracted, it is opposite to the position of the insertion hole 13. The cover 9 is flexible so as not to hinder the movement of the first locking tongue 82.

[0045] When the motor is running, under the limiting action of the second mounting hole 22, the output shaft of the motor drives the cam to rotate, and then drives the first locking tongue 82 to move linearly through the connecting rod hinged to it. Since the first locking tongue 82 is set to correspond to the insertion hole 13 when it is retracted, the first locking tongue 82 can be extended into the insertion hole 13 under the action of the first driving device 81, thereby completing the positioning of the inner cylinder 1, and the first locking tongue 82 can be retracted from the first insertion hole 13, thereby completing the release of positioning.

[0046] Furthermore, the second mounting hole 22 and the first locking tongue 82 can be sealed without the cover 9, and can be replaced with a flexible sealing gasket, etc.; or the first locking tongue 82 can be limited without the second mounting hole 22. For example, when the first drive device 81 is replaced with a structure of motor and gear rack, that is, the output shaft of the motor is fixedly connected to the gear, and the gear meshes with the rack. In this case, a slide can be provided on the outer cylinder 2, and the rack can be slidably set in the slide and pass through the second mounting hole 22. The rack can be sealed and connected to the periphery of the second mounting hole 22 through the cover 9, and after sealing and passing through the hole of the cover 9, it is connected to the first locking tongue 82, etc., wherein there is a movable gap between the rack and the second mounting hole 22.

[0047] Furthermore, the position of the first locking tongue relative to the insertion hole 13 when it retracts may not be opposite. For example, the first locking tongue may be arc-shaped, and the inner wall of the outer cylinder 2 may be provided with an arc-shaped track that is adapted to the first locking tongue to limit the first locking tongue. The first locking tongue is located on the arc-shaped track, and one end of the arc-shaped track is opposite to the insertion hole 13, so that the first end of the first locking tongue can slide out of the arc-shaped track and extend into the insertion hole 13 under the action of the first driving device. When the first locking tongue retracts, the first end slides back into the arc-shaped track. In this case, the second end of the first locking tongue extends out of the other end of the arc-shaped track and out of the second mounting hole 22, and the second end can be sealed and connected to the second mounting hole 22 by a flexible sealing gasket / cover. The first driving device may be a combination of a motor and a gear, wherein the gear meshes with the second end of the first locking tongue.

[0048] In one possible implementation, the inner wall of the inner drum 1 is provided with lifting ribs 12, which together with the inner wall form a cavity, and the insertion hole 13 is located in the cavity. It can be understood that the function of the lifting ribs 12 is to lift the clothes to a higher position when the inner drum 1 rotates, thereby creating an up-and-down tumbling motion to achieve the purpose of washing the clothes.

[0049] The advantage of this arrangement is that when the first locking tongue 82 is inserted into the insertion hole 13, since the insertion hole 13 is located in the cavity formed by the lifting rib 12 and the inner wall of the inner tube 1, the first locking tongue 82 can avoid interfering with the clothes in the inner tube 1 and can avoid wear on the first locking tongue 82.

[0050] Implementation Method 2: The positioning device includes a second driving device and a second locking tongue. The driving body that drives the inner cylinder 1 to rotate has a second groove. Under the drive of the second driving device, the second locking tongue can extend into the second groove and retract from the second groove. The second driving device can take various forms, such as a combination of an electric push rod, a motor, and a gear rack. The second driving device can be installed on the outer bottom wall of the outer cylinder 2 or on the inner wall of the housing.

[0051] The driving body that drives the inner cylinder 1 to rotate refers to any structure that enables the inner cylinder 1 to rotate under the action of the driving body.

[0052] As one possible implementation method, refer to Figure 2 The motor driving the inner cylinder 1 to rotate is a direct drive motor 10, and the driving body is the outer rotor of the direct drive motor 10 (not shown in the figure). That is, a second groove (not shown in the figure) is provided on the outer rotor. Under the drive of the second drive device 83, the second locking tongue 84 can extend into the second groove and can retract from the second groove.

[0053] When the inner cylinder 1 is positioned, the second drive device 83 is activated, causing the second locking tongue 84 connected to the second drive device 83 to extend into the second groove on the outer rotor. It can be understood that the outer rotor of the direct drive motor 10 is connected to the inner cylinder 1 through a transmission shaft, so the inner cylinder 1 rotates when the outer rotor rotates. Therefore, after the second locking tongue 84 extends into the second groove of the outer rotor, the outer rotor can be positioned, and thus the inner cylinder 1, which rotates coaxially with it, can be positioned. When the second locking tongue 84 retracts from the second groove, the positioning of the inner cylinder 1 is released.

[0054] In another possible implementation, not shown in the illustrations, a first pulley is mounted on the transmission shaft that drives the inner cylinder 1 to rotate, and a second pulley is mounted on the output shaft of the motor. The first and second pulleys are connected by a belt, and the driving element is either the first or second pulley. Specifically, the first or second pulley has a second groove. Under the drive of the second driving device, the second locking tongue can extend into and retract from the second groove. In this embodiment, the motor driving the inner cylinder 1 to rotate can be fixed to the inner wall of the housing or the outer wall of the outer cylinder 2.

[0055] When the inner cylinder 1 is positioned, the second drive device is activated, causing the second locking tongue connected to the second drive device to extend into the second groove of the first pulley or the second pulley, thereby stopping the first pulley or the second pulley from rotating. As a result, the inner cylinder 1 also stops rotating, thus achieving the positioning of the inner cylinder 1. When the second locking tongue 84 retracts from the second groove, the positioning of the inner cylinder 1 is released.

[0056] To avoid the venting element 3 interfering with the rotation of the inner drum 1 when the inner drum 1 rotates, thereby affecting the washing operation, the present invention adopts the following two possible implementation methods.

[0057] A first possible implementation: The garment processing equipment further includes a third driving device 5, which is connected to a venting component 3. Driven by the third driving device 5, the venting component 3 can extend and retract on both the inner and outer sides of the vent hole 11. When the venting component 3 extends into the inner side of the vent hole 11, the air outlet 32 ​​is located in the water storage area. That is, when it is necessary to introduce gas into the water storage area of ​​the inner drum 1, the third driving device 5 drives the venting component 3 to extend into the water storage area of ​​the inner drum 1, and the gas discharged from the air outlet 32 ​​can be directly introduced into the water storage area, making full use of the energy generated by the bubbles to improve the washing effect. When it is not necessary to introduce gas into the water storage area of ​​the inner drum 1, the third driving device 5 drives the venting component 3 to retract from the water storage area of ​​the inner drum 1 to the outside of the inner drum 1 to avoid interfering with the rotation of the inner drum 1.

[0058] Possibly, such as Figure 3 and Figure 4 As shown, the ventilation component 3 is a rod 33, and an airflow channel is formed inside the rod 33 along its axial direction. The air inlet 31 and the air outlet 32 ​​are both connected to the airflow channel. The third driving device 5 includes a motor 51 and a transmission assembly 52. ​​The motor 51 is connected to the rod 33 through the transmission assembly 52 to drive the rod 33 to contract on both the inner and outer sides of the ventilation hole 11.

[0059] The outer cylinder 2 of the garment processing equipment is provided with a first mounting hole 21. The garment processing equipment also includes a sealing element 6, which includes a flexible cover 61. The bottom end of the flexible cover 61 is open, and the open end 612 is sealed to the first mounting hole 21. The top end of the flexible cover 61 is provided with a connecting hole 611. The first end of the rod 33 is connected to the transmission assembly 52. ​​The second end of the rod 33 is provided through the connecting hole 611 from the inside of the flexible cover 61, and the connecting hole 611 is fixedly and sealed to the rod 33. When the third driving device 5 drives the rod 33 to extend into the inside of the vent hole 11 (i.e., inside the inner cylinder 1), the flexible cover 61 can form a seal with the vent hole 11. It is understood that the flexible cover 61 is a flexible cover with an internal cavity, its bottom end is open, the opening 612 communicates with the cavity, and the opening 612 is sealed to the first mounting hole 21. Its top end refers to the side away from the opening 612. The wall of the flexible cover 61 is preferably corrugated, but it can also be non-corrugated. The material of the flexible cover 61 can be rubber or silicone, etc. The connection hole 611 and the rod 33 can be fixed and sealed in various ways, such as interference fit between the connection hole 611 and the rod 33, or connection through a sealing gasket, etc. In addition, the air inlet 31 of the rod 33 can be located at its first end or on its side wall, and its air outlet 32 ​​is preferably at its second end, but it can also be located on its side wall. In this case, in order to effectively ensure that the rod 33 can extend and retract, the connecting pipe 7 connected to the gas outlet 41 of the gas generating device 4 can be a corrugated pipe 34 or a flexible hose that can deform.

[0060] When gas needs to be introduced into the water storage area of ​​the inner drum 1, the third drive device 5 drives the rod 33 to extend into the water storage area of ​​the inner drum 1 through the vent hole 11. At this time, since the rod 33 is fixedly and sealed to the connecting hole 611, when the rod 33 makes a linear movement towards the vent hole 11, it will drive the flexible cover 61 to move together towards the vent hole 11 until the flexible cover 61 abuts against the vent hole 11, thereby forming a seal between the flexible cover 61 and the vent hole 11, thus preventing the gas introduced into the water storage area from escaping from the vent hole 11 to between the inner drum 1 and the outer drum 2, resulting in the loss of bubble volume. Especially when there is a lot of clothes in the inner drum 1, it can avoid the deterioration of the washing effect. In addition, since the bottom end of the flexible cover 61 forms a seal with the first mounting hole 21, it can prevent the washing water from flowing out of the first mounting hole 21. The above setting can realize that the flexible cover 61 can simultaneously form two seals at the vent hole 11 and the first mounting hole 21, realizing multiple uses with one part and reducing the cost of use.

[0061] Furthermore, the sealing element 6 also includes a housing 62 with an open top. The bottom end of the housing 62 is sealed and installed in the first mounting hole 21. The sealing connection can be achieved in various ways, such as by interference fit between the housing 62 and the first mounting hole 21, or by sealing gaskets. The bottom end of the flexible cover 61 is connected to the inner bottom wall of the housing 62, and the top end of the flexible cover 61 is sealed and connected to the opening 621, such as by corrugated rubber or by flat silicone. A second through hole 622 is also formed on the inner bottom wall of the housing 62. The second through hole 622 is located in the flexible cover 61. The rod 33 passes through the second through hole 622 and has a clearance with the second through hole 622 so that the rod 33 can move in the second through hole 622.

[0062] The bottom end of the flexible cover 61 is sealed to the first mounting hole 21 via the bottom wall of the outer shell 62, thus preventing washing water from flowing out of the first mounting hole 21. Its top end is sealed to the opening 621, preventing washing water from entering the interior of the outer shell 62. This ensures that internal parts do not come into prolonged contact with washing water, protecting them from damage and extending their service life. The second through hole 622 on the bottom wall of the outer shell 62 restricts the linear movement of the rod 33, allowing it to be accurately inserted into the vent hole 11. The overall design of the sealing element 6 requires minimal structural modification to the inner cylinder 1 and outer cylinder 2, and is easy to install and disassemble. Furthermore, a spring is also provided inside the flexible cover 61. One end of the spring is connected to the inner top wall of the flexible cover 61, and the other end is connected to the inner bottom wall of the outer shell 62, thus providing support for the flexible cover 61.

[0063] Possibly, the transmission assembly 52 is a cam-linkage mechanism, meaning the motor 51 is connected to the first end of the rod 33 via the cam-linkage mechanism. It can be understood that the cam-linkage mechanism includes a cam and a connecting rod. The output shaft of the motor 51 is fixedly connected to the cam, the cam is hinged to the connecting rod, and the connecting rod is hinged to the first end of the rod 33. Thus, when the output shaft of the motor 51 rotates, it can drive the rod 33 to move linearly, achieving the contraction of the rod 33 on both the inner and outer sides of the vent 11. The air inlet 31 of the vent 3 can be located on the side wall of the rod 33. The end of the rod 33 away from the inner cylinder 1 has no opening and is hinged to the connecting rod. The motor 51 can be fixed in various ways; for example, a bracket can be installed on the outer wall of the outer cylinder 2 or the housing, and the motor 51 can be fixedly mounted on the bracket, or the motor 51 can be directly mounted on the inner wall of the housing or the outer wall of the outer cylinder 2.

[0064] Furthermore, the implementation of the third driving device 5 driving the venting member 3 to extend and retract on both the inner and outer sides of the vent 11 is not limited to the above implementation; it is possible that, for example... Figure 5 and Figure 6As shown, the venting component 3 is a bellows 34, and a pressure chamber 341 is formed inside the wall of the bellows 34. A pressure port 342 is provided on the wall, and the pressure port 342 communicates with the pressure chamber 341. The third driving device 5 is a pneumatic device or a hydraulic device. The outlet of the third driving device 5 is connected to the pressure port 342. The end of the bellows 34 away from the inner cylinder 1 is connected to the gas outlet 41. In this case, the other end of the bellows 34 is its gas outlet 32.

[0065] The pneumatic device can take various forms, such as an air pump or any existing or future device capable of drawing and blowing air. The hydraulic device can include a bidirectional hydraulic pump and a hydraulic tank. The outlet of the hydraulic tank is connected to the first opening of the bidirectional hydraulic pump, and the second opening of the hydraulic pump is connected to the pressure port 342. That is, when hydraulic oil needs to be injected, the bidirectional hydraulic pump operates, causing the hydraulic oil in the hydraulic tank to flow into the pressure chamber 341 through the first opening, the second opening, and the pressure port 342. When hydraulic oil needs to be released, the bidirectional hydraulic pump operates, causing the hydraulic oil to flow back to the hydraulic tank from the pressure chamber 341 through the pressure port 342, the second opening, and the first opening. Alternatively, the hydraulic device can be a piston-type hydraulic cylinder, including a cylinder body, piston, connecting rod, and drive component. The cylinder body has an oil hole and a mounting hole, with the oil hole connected to the pressure port 342. The piston is... Within the cylinder body, a sealing sliding mechanism is installed along the cylinder body axially, dividing the internal cavity into a first chamber and a second chamber. An oil hole is located in the first chamber, and a mounting hole is located in the second chamber at the end of the cylinder body. One end of a connecting rod is connected to the piston, and the other end passes through the mounting hole and connects to a drive component outside the cylinder body. Hydraulic oil is located in the first chamber. The drive component can be any device capable of driving the piston to make linear motion via the connecting rod, such as a combination of a motor and a gear rack. When the drive component drives the piston toward the first chamber, the volume of the first chamber decreases, and the hydraulic oil is discharged from the oil hole into the pressure chamber 341. When the drive component drives the piston toward the second chamber, the volume of the first chamber increases, and the hydraulic oil in the pressure chamber 341 is drawn back to the first chamber through the oil hole. Alternatively, the hydraulic device can also be any existing or future device capable of achieving oil discharge and oil suction.

[0066] Furthermore, it is understood that the wall of the bellows 34 of the present invention can be entirely corrugated or partially corrugated; for example, the middle part is corrugated, and the two ends are flat. The bellows 34 is sealed in the first mounting hole 21 in various ways. For example, one end of the bellows 34 is not corrugated, and an annular metal sheet is tightly fitted around that end. The first mounting hole 21 on the outer cylinder 2 is sealed to the metal sheet by a sealing gasket. Alternatively, the bellows 34 is directly bonded to the first mounting hole 21 with waterproof adhesive. The bellows 34 can extend out of the first mounting hole 21, and the pressure port 342 is located on the outer wall of the first mounting hole 21, thereby facilitating the connection between the pressure port 342 and the outlet of the third driving device 5.

[0067] When gas needs to be introduced into the water storage area of ​​the inner cylinder 1, the pneumatic or hydraulic device operates, allowing gas or hydraulic oil to enter the pressure chamber 341 of the bellows 34 through the pressure port 342, thereby pressurizing the pressure chamber 341. As a result, the bellows 34 begins to elongate, allowing it to extend into the vent hole 11. When gas does not need to be introduced into the water storage area of ​​the inner cylinder 1, the pneumatic or hydraulic device performs a depressurization operation, allowing the gas or hydraulic oil in the pressure chamber 341 to be discharged through the pressure port 342, thereby depressurizing the pressure chamber 341 and allowing the bellows 34 to retract to the outside of the inner cylinder 1 to prevent interference.

[0068] In this case, the aforementioned flexible cover 61 can be further configured, with the bottom opening of the flexible cover sealed to the first mounting hole 21, one end of the bellows 34 sealed to the first mounting hole 21, and the other end of the bellows 34 passing through the interior of the flexible cover and exiting through the connecting hole 611 at the top of the flexible cover, with the connecting hole 611 sealed to the bellows 34. When the third driving device 5 drives the bellows 34 to extend into the inner side of the vent hole 11, the flexible cover can form a seal with the vent hole 11. This prevents gas introduced into the water storage area from escaping through the vent hole 11 to the space between the inner cylinder 1 and the outer cylinder 2, thus preventing the loss of bubble volume. The structure of the flexible cover is similar to that described above.

[0069] In a preferred embodiment, the inner wall of the inner cylinder 1 of the present invention has a first through hole on the lifting rib 12, and the ventilation hole 11 is provided in the cavity formed by the lifting rib 12 and the inner wall.

[0070] This invention utilizes the existing structure of the garment processing equipment—the lifting rib 12—to prevent the garment from contacting the ventilator 3 after it is inserted into the water storage area of ​​the inner cylinder 1 through the vent hole 11. This is because the vent hole 11 is located in the cavity formed by the lifting rib 12 and the inner wall of the inner cylinder 1. In other words, it avoids interference between the ventilator 3 and the garment, thereby preventing potential wear and tear on the ventilator 3 and damage to the garment. Furthermore, since the lifting rib 12 and the inner wall of the inner cylinder 1 form a small enclosed space, the energy loss of the bubbles is minimal. As a result, the bubbles can still reach the garment through the first through hole on the lifting rib 12 to form cavitation bubbles, effectively removing dirt from the garment.

[0071] The second possible implementation: the air outlet of the vent is located between the inner cylinder 1 and the outer cylinder 2, and is correspondingly set with the vent hole 11, that is, the gas enters the water storage area of ​​the inner cylinder 1 directly through the air outlet of the vent and the vent hole 11.

[0072] The specific form of the venting component can be various. For example, it can be a hollow rod, with one end (air inlet 31) connected to the gas outlet 41 of the gas generator 4, and the other end being an outlet 32, which is correspondingly set with the vent hole 11. Alternatively, the venting component 3 can be a connecting pipe 7 directly connected to the gas outlet 41 of the gas generator 4. One end of the outlet 32 ​​of the connecting pipe 7 extends directly from the first mounting hole 21 into the space between the inner cylinder 1 and the outer cylinder 2, and is correspondingly set with the vent hole 11. The venting component 3 and the first mounting hole 21 can be directly sealed together by a sealing gasket. Alternatively, the venting component 3 can be the first mounting hole 21, which is correspondingly set with the vent hole 11. In this case, the first mounting hole 21 extends a predetermined length from the inner wall of the outer cylinder 2 toward the inner cylinder 1, and the gas outlet 41 of the gas generator 4 is sealed together with the first mounting hole 21. When the venting component 3 is a connecting pipe 7 that is directly connected to the gas outlet 41 of the gas generating device 4, the connecting pipe 7 can be inserted through the hole provided on the window gasket connecting the outer cylinder opening and the housing instead of through the first mounting hole 21, so as to form an effective seal. Then the air outlet 32 ​​of the connecting pipe 7 is correspondingly set with the vent hole 11. In this case, the vent hole 11 can be set on the front side of the inner cylinder 1, such as at the inner cylinder opening.

[0073] The above-described setup only slightly reduces the washing effect, but it avoids interference between the air vent 3 and the clothes, preventing wear and tear on the air vent 3 and damage to the clothes. Furthermore, it eliminates the need for a drive unit, reducing operating costs. Additionally, this setup does not hinder the rotation of the inner drum 1, allowing the gas generator 4 to remain running while the inner drum 1 rotates. The optimal cleaning power for clothes is achieved when the air outlet 32 ​​of the air vent 3 aligns with the air vent 11 of the inner drum 1.

[0074] As one possible implementation, the garment handling equipment also includes a position sensing device, which is configured to be triggered when the inner drum 1 rotates to a set position to control the inner drum 1 to stop rotating and to position the inner drum 1 by the positioning device 8.

[0075] The specific forms of position sensing devices include various types. For example, a position sensing device may include a Hall sensor and a magnet. The Hall sensor is disposed on the side wall of the outer cylinder 2, and the magnet is disposed on the side wall of the inner cylinder 1. When the inner cylinder 1 rotates to a set position, the Hall sensor and the magnet are positioned opposite each other to trigger a signal. Alternatively, a Hall sensor may be disposed on the outer bottom wall of the outer cylinder 2 (at the bottom side of the outer cylinder 2 in the axial direction), and a magnet may be disposed on the outer rotor of the direct drive motor 10 that drives the inner cylinder 1 to rotate. When the inner cylinder 1 rotates to a set position, the Hall sensor and the magnet are positioned opposite each other to trigger a signal. Or, a position sensor may include a signal switch and a signal contact. The signal switch is disposed at the opening of the outer cylinder, and the signal contact is disposed at the opening of the inner cylinder. When the inner cylinder 1 rotates to a set position, the signal switch and the signal contact come into contact to trigger a signal.

[0076] The set position to which the inner drum 1 rotates can be the position where the positioning device 8 can position the inner drum 1. For example, the inner drum 1 can rotate to the position where the first locking tongue 82 can extend into the insertion hole 13, or the inner drum 1 can rotate to the position where the second locking tongue can extend into the second groove. Alternatively, the inner drum 1 can rotate to a preset distance before the positioning device 8 can position the inner drum 1. Since the inner drum 1 may continue to rotate slowly after the motor stops rotating by controlling the inner drum 1 with a large current, the preset distance is used to make the rotation speed of the inner drum 1 continue to decrease before the positioning device 8 positions the inner drum 1. This is more conducive to protecting the positioning device 8 and the washing machine from damage.

[0077] In the above configuration, when the inner cylinder 1 rotates to the set position, the position sensor is triggered and sends a trigger signal, which is then received by the controller. If the set position is a position that can position the inner cylinder 1, after the controller receives the trigger signal, it controls the inner cylinder 1 to stop rotating and simultaneously controls the positioning device 8 to operate. If the set position is a position where the inner cylinder 1 rotates to a preset distance before the positioning device 8 can position the inner cylinder 1, after the controller receives the trigger signal, it controls the inner cylinder 1 to stop rotating and then allows the inner cylinder 1 to continue rotating a preset distance. After the inner cylinder 1 continues to rotate a preset distance, the positioning device 8 is then activated. This allows for precise positioning of the inner cylinder 1, facilitating the entry of the gas generated by the gas generator 4 into the water storage area of ​​the inner cylinder 1 through the gas outlet 32 ​​and the vent 11.

[0078] In addition, such as Figure 7 As shown, the present invention also provides a control method for a garment processing device, the control method comprising:

[0079] Step S100: During the washing process, control the rotation of the inner drum.

[0080] Step S200: When the inner cylinder rotates to the set position, control the inner cylinder to stop rotating.

[0081] Step S300: Control the positioning device to position the inner cylinder.

[0082] Step S400: Start the gas generating device.

[0083] Step S500: After a preset time has elapsed, the positioning device releases the inner cylinder from its position.

[0084] One approach is to incorporate an air-bubble program into the washing cycle of the garment processing equipment. For example, in the washing cycle of the garment processing equipment, the motor controlling the rotation of the inner drum rotates according to a preset rotation-to-stop ratio. Therefore, when the motor operating according to the preset rotation-to-stop ratio is in the stop-rotation range during the washing cycle, the air-bubble program can be executed, i.e., controlling the rotation of the inner drum until it reaches a set position, at which point the inner drum stops rotating. If the set position is a position where the positioning device can position the inner drum, then after controlling the inner drum to stop rotating, the positioning device is simultaneously activated to position the inner drum. Positioning can be achieved through the aforementioned method of positioning the inner drum or positioning motor. If the set position is a preset distance before the positioning device can position the inner drum, then after controlling the inner drum to stop rotating, the inner drum continues to rotate a preset distance, and after the inner drum continues to rotate a preset distance, the positioning device is activated. Positioning can be achieved through the aforementioned method of positioning the inner drum or positioning motor, thereby completing the positioning of the inner drum. The method for determining the preset distance of the inner cylinder's rotation can be as follows: after receiving a trigger signal, determine whether the inner cylinder has rotated to the preset distance after a set time. The set time is obtained based on controlling the rotation speed of the inner cylinder. The set position is the set position described in the above embodiment. There are various ways to determine when the inner cylinder has rotated to this set position. For example, it can be done by setting the position sensing device mentioned above, or it can be determined based on the rotation speed and time of the motor driving the inner cylinder. That is, the rotation speed and time of the motor determine the rotation position of the inner cylinder. Therefore, when both the rotation speed and time of the motor reach the set values, it can be determined that the inner cylinder has rotated to the set position.

[0085] Of course, when the inner cylinder is in the rotation range while operating at a preset rotation-to-stop ratio, the inner cylinder can be directly controlled to rotate to a set position. For example, the rotation speed of the inner cylinder can be reduced to a preset speed. In this case, when the inner cylinder rotates to the set position, the inner cylinder can be controlled to stop rotating, and then the positioning device can be controlled to position the inner cylinder.

[0086] After the positioning device positions the inner drum, it prevents the inner drum from continuing to rotate due to the load of clothes. This ensures that the gas generated by the gas generator can enter the water storage area of ​​the inner drum through the air outlet and vent, thereby guiding the gas generated by the gas generator into the water storage area of ​​the inner drum to remove stains from the clothes and effectively dissolve the detergent. The implementation method where the gas generated by the gas generator enters the water storage area of ​​the inner drum through the air outlet and vent is the first or second possible implementation method described above to avoid interference of the venting device with the rotation of the inner drum.

[0087] When the air outlet is located between the inner and outer drums and corresponds to the vent hole, after the positioning device positions the inner drum, the gas generator can be directly started. This allows most of the gas to enter the water storage area of ​​the inner drum sequentially through the air outlet of the vent and the vent hole of the inner drum, thereby improving the washing effect. After the step of "controlling the gas generator to start," the step of "controlling the positioning device to release the inner drum after a preset time" is also included. Furthermore, the gas generator can be turned off simultaneously. When the garment processing equipment also includes a third drive device connected to the vent, the vent can extend and retract on both sides of the vent hole under the drive of the third drive device. After the step of "controlling the positioning device to position the inner drum", the method further includes the step of "controlling the third drive device to drive the vent to extend into the inside of the vent hole", so that gas is directly introduced into the water storage area of ​​the inner drum through the air outlet of the vent, thereby improving the cleaning ability and washing effect. When the vent extends into the inside of the vent hole, the air outlet is located in the water storage area of ​​the inner drum. After the step of "controlling the third drive device to drive the vent to extend into the inside of the vent hole", the control method further includes "after a preset time, controlling the third drive device to drive the vent to retract to the outside of the vent hole; controlling the positioning device to release the positioning of the inner drum". Furthermore, the gas generating device can be turned off at the same time. The aforementioned preset time can be set by the user or calculated based on the preset time period before the inner drum rotates according to the preset rotation-stop ratio in the original washing program of the washing machine. In other words, within the preset time period before the inner drum rotates according to the original washing program of the washing machine, the positioning device can be directly controlled to release the positioning of the inner drum, or the vent can be controlled to retract to the outside of the vent hole, and the positioning device can be controlled to release the positioning of the inner drum. The way to control the positioning device to release the positioning of the inner drum is to control the first drive device to drive the first locking tongue to retract from the insertion hole or control the second drive device to drive the second locking tongue to retract from the second groove, so that after the bubble washing of clothes is completed, the rotation of the inner drum can be undisturbed, thereby completing the efficient washing of clothes.

[0088] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above embodiments so that the present invention can be applied to more specific application scenarios.

[0089] For example, although the present invention is described in terms of a flexible cover 61, this is not intended to limit the scope of protection of the present invention. The arrangement can be adjusted, such as omitting the flexible cover 61, or connecting the first end of the rod 33 to the first mounting hole 21 through a flexible sealing gasket, that is, compensating for the movement distance of the rod 33 through the flexible sealing gasket. These are all within the scope of protection of the present invention and do not deviate from the principle of the present invention.

[0090] For example, although the present invention is described with the second through hole 622 formed on the bottom wall of the outer shell 62, the second through hole 622 being disposed in the flexible cover 61, the rod 33 passing through the second through hole 622, and having an movable gap with the second through hole 622, this is not intended to limit the scope of protection of the present invention. For example, the outer shell 62 can be omitted, the rod 33 can pass through the first mounting hole 21, the first mounting hole 21 and the rod 33 can have an movable gap, and the bottom end of the flexible cover 61 can be sealed around the first mounting hole 21, etc. These are all within the scope of protection of the present invention without departing from the principle of the present invention.

[0091] For example, as an alternative implementation, although the third drive device 5 of the present invention is described as a motor 51 and a cam linkage mechanism, this is not intended to limit the scope of protection of the present invention. Its configuration can be adjusted. For instance, the third drive device 5 can be a motor 51 and a gear and rack mechanism, with the output shaft of the motor 51 fixedly connected to the gear, the gear meshing with the rack, and the rack connected to the first end of the rod 33. A guide member can be provided on the outer wall of the outer cylinder, and the guide member has a strip-shaped groove. The rack is movably disposed in the groove to guide the rack, etc. In this case, the rod 33 may not be sealed to the first mounting hole 21; instead, the rack may be sealed to the first mounting hole 21 through a flexible sealing gasket, etc. These modifications do not deviate from the principles of the present invention and are all within the scope of protection of the present invention.

[0092] Those skilled in the art will understand that the aforementioned garment processing equipment includes some well-known structures, such as processors, controllers, and memories.

The processors include, but are not limited to, CPLD / FPGA, DSP, ARM processors, and MIPS processors. To avoid unnecessarily obscuring the embodiments of this disclosure, these well-known structures are not shown in the accompanying drawings.

[0093] Although the steps in the above embodiments are described in the above order, those skilled in the art will understand that in order to achieve the effect of this embodiment, different steps do not need to be executed in such an order. They can be executed simultaneously (in parallel) or in reverse order. For example, the steps of "controlling the inner cylinder to stop rotating and controlling the positioning device to operate" can be executed simultaneously.

[0094] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
