Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of sealing structures, and in particular, to a sealing element and a clothes processing device. Background Art

[0002] At present, washing machines in related technologies generally use oil seals for waterproofing. However, due to manufacturing precision and assembly tolerances, the sealing disk and the oil seal of the washing machine may not be coaxial, causing deformation, wear, and leakage of the oil seal lip. Summary of the Invention

[0003] The embodiments of the present invention aim to solve at least one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of an embodiment of the present invention provides a sealing member.

[0005] A second aspect of the embodiments of the present invention provides a clothes treating apparatus.

[0006] In view of this, according to a first aspect of an embodiment of the present invention, a seal is provided for a clothing processing device, the clothing processing device including a sealing disk and an outer barrel, the seal including: a main body; a sealing portion, arranged on the main body, the sealing portion being used to be sealed and connected to the sealing disk; a fixing portion, arranged on the main body, the fixing portion being used to set the seal on the outer barrel; a transition portion, arranged between the sealing portion and the fixing portion, the transition portion being able to cause relative movement between the sealing portion and the fixing portion.

[0007] The seal provided by embodiments of the present invention includes a body, a sealing portion, a fixing portion, and a transition portion. Specifically, the sealing portion is configured to sealably connect with a sealing disk of a laundry processing device. The sealing portion secures the seal to the outer tub of the laundry processing device via the fixing portion, thereby enabling the seal to form a seal between the outer tub and the sealing disk. It is understood that the sealing disk is disposed between the inner tub and the clutch of the laundry processing device, so that the seal and the sealing disk form a seal between the outer tub and the clutch, and between the inner tub and the clutch, thereby preventing water leakage during operation of the laundry processing device. Furthermore, a transition portion is disposed between the sealing portion and the fixing portion. The transition portion enables relative movement between the sealing portion and the fixing portion. Specifically, the transition portion enables relative movement between the fixing portion and the sealing portion in radial and axial directions. During operation of the laundry processing device, the relative movement generated by the transition portion effectively offsets misalignment between the seal and the sealing disk caused by manufacturing precision and assembly tolerances. This effectively prevents deformation and wear of the seal during operation, which in turn reduces its service life. This prevents water leakage during operation of the laundry processing device and improves the user experience.

[0008] In addition, since vibrations are generated during the operation of the clothing processing device, the transition portion can also offset the wear between the seal and the sealing disk caused by the vibrations generated during the operation of the clothing processing device, further extending the service life of the seal and the sealing disk of the clothing processing device, and thus extending the service life of the clothing processing device.

[0009] It should be noted that the sealing portion, the fixing portion, and the transition portion can be an integrated structure. This integrated structure has good mechanical properties, thereby ensuring the connection strength between the sealing portion, the transition portion, and the fixing portion, thereby ensuring the sealing effect of the seal. In addition, the integrated structure can also facilitate the processing and production of the seal, thereby reducing the service life of the seal.

[0010] It should also be noted that the seal can be set to a rubber material. The hardness of the rubber material is relatively low, which can ensure the sealing effect of the seal. The rubber material has a certain degree of deformation, which can offset the problem of misalignment between the seal and the sealing disk due to manufacturing precision and assembly tolerance, and thus effectively prevent the seal from deforming and wearing during the operation of the clothing processing device, thereby reducing the service life of the seal.

[0011] In addition, the seal provided by the above technical solution of the present invention also has the following additional technical features:

[0012] In a possible design, the sealing portion includes at least one sealing lip and an elastic member, wherein the at least one sealing lip is used for sealing connection with the sealing disk, and the elastic member is arranged on a side of the sealing portion facing away from the at least one sealing lip.

[0013] In this design, the sealing part is defined as including at least one sealing lip and an elastic part. Specifically, the sealing part is sealed to the sealing disk through at least one sealing lip. It can be understood that since the sealing part is fixed on the outer barrel, the distance between the sealing part of the sealing part and the sealing disk is certain. By forming a moving seal between at least one sealing lip and the sealing disk, the contact area between the sealing part and the sealing disk can be reduced, thereby increasing the mutual force between the sealing part and the sealing disk, improving the sealing effect between the seal and the sealing disk, and then improving the sealing effect between the outer barrel and the clutch, further avoiding water leakage during the movement of the clothing processing device.

[0014] In addition, an elastic member is provided on the side away from at least one sealing lip. Specifically, the elastic member is sleeved on one of the at least one sealing lips, so that the elastic member undergoes elastic deformation. When the elastic member undergoes elastic deformation, a restoring force is generated. The restoring force makes one of the at least one sealing lips closer to the sealing disk, further improving the sealing effect between the sealing member and the sealing disk.

[0015] It should be noted that the elastic member may be a spring.

[0016] In a possible design, the clothing processing device further includes a mounting portion, and the sealing member further includes a rotation-stopping portion, which is disposed between the transition portion and the sealing portion and is configured to cooperate with the mounting portion of the clothing processing device.

[0017] In this design, the clothing processing device also includes a mounting portion, which limits the seal to also include a rotation-stopping portion. Specifically, a rotation-stopping portion is further provided between the transition portion and the sealing portion. The rotation-stopping portion is used to cooperate with the mounting portion of the clothing processing device, so that during the operation of the clothing processing device, the sealing portion of the seal can be prevented from rotating together with the inner barrel through the limiting cooperation between the rotation-stopping portion and a part of the mounting portion. The fixed portion of the seal does not move, causing the seal itself to twist, resulting in wear of the seal or even damage, thereby further extending the service life of the seal.

[0018] In a possible design, the at least one sealing lip includes a first sealing lip and a second sealing lip, wherein the second sealing lip is arranged on a side of the first sealing lip facing away from the rotation stop.

[0019] In this design, at least one sealing lip is defined as comprising a first sealing lip and a second sealing lip. Specifically, the second sealing lip is disposed on the side of the first sealing lip facing away from the anti-rotation portion, and the elastic member is sleeved over the first sealing lip, thereby ensuring a tight fit between the first sealing lip and the sealing disc, improving the sealing effectiveness of the seal. Furthermore, the second sealing lip is disposed on the side of the first sealing lip facing away from the anti-rotation portion, i.e., above the first sealing lip, thereby forming a first sealing area between the first and second sealing lips. It is understood that lubricating oil can be provided within the first sealing area to reduce wear between the sealing portion and the sealing disc during operation of the clothing processing device, thereby extending the service life of the seal. Providing the second sealing lip above the first sealing lip prevents water, dust, or lint from entering the first sealing lip from above, potentially causing the first sealing lip to fail. Furthermore, providing the second sealing lip above the first sealing lip prevents lubricating oil from leaking from the first sealing area between the first and second sealing lips, potentially causing wear between the sealing portion and the sealing disc, further extending the service life of the seal.

[0020] In a possible design, the at least one sealing lip further includes a third sealing lip, which is arranged between the first sealing lip and the second sealing lip.

[0021] This design specifies that at least one sealing lip also includes a third sealing lip. Specifically, the third sealing lip is located between the first and second sealing lips. This further prevents water, dust, or lint from entering the first sealing lip, potentially causing sealing failure. It also further prevents lubricant leakage from causing wear between the seal and the sealing disc, extending the seal's service life and further ensuring its sealing effectiveness.

[0022] It can be understood that the second sealing lip is close to the side of the inner barrel, and thus during the operation of the clothing processing device, it is easy for water, dust or hair to enter the first sealing lip from above. Therefore, by arranging the third sealing lip between the first sealing lip and the second sealing lip, the sealing effect of the seal can be further guaranteed.

[0023] In a possible design, the at least one sealing lip further includes a fourth sealing lip, which is arranged on a side of the first sealing lip close to the rotation stop portion.

[0024] In this design, it is defined that at least one sealing lip also includes a fourth sealing lip. Specifically, a fourth sealing lip is further provided on the side close to the anti-rotation portion, that is, the fourth sealing lip is provided below the first sealing lip, so that a second sealing area is formed between the first sealing lip and the fourth sealing lip. It is understood that lubricating oil can be provided in the second sealing area to further reduce the wear between the sealing portion and the sealing disk of the seal during the operation of the clothing processing device, thereby extending the service life of the seal. By providing the fourth sealing lip below the first sealing lip, it is possible to prevent water, dust, or hair from entering the position where the first sealing lip is located from below, thereby preventing the first sealing lip from sealing failure. In addition, providing the fourth sealing lip below the first sealing lip can also prevent the lubricating oil in the second sealing area between the first and fourth sealing lips from leaking, thereby preventing the sealing portion and the sealing disk from wearing, thereby further extending the service life of the seal.

[0025] In a possible design, the sealing member further includes a first reinforcement member, which is arranged on the body near the sealing portion.

[0026] In this design, it is defined that the seal also includes a first reinforcement. Specifically, the first reinforcement is provided at a position of the main body near the sealing part, that is, the first reinforcement is provided at a position of the main body near the sealing part, which can enhance the rigidity, strength and roundness of the position where the sealing part is located. Since during the operation of the clothing processing device, the inner barrel of the clothing processing device will rotate at high speed for washing or dehydration, by providing the first reinforcement at a position close to the sealing part, the structural strength at this position can be improved, thereby preventing the seal from twisting during the high-speed rotation of the inner barrel, which may cause the sealing failure of the seal, and further extend the service life of the seal.

[0027] Among them, it should be noted that the first reinforcement can be made of metal skeleton material, and the metal skeleton material can be coated with rubber material, that is, the metal skeleton material is set in the seal. It can improve the stiffness, strength and circularity of the sealing part, while ensuring the connection effect between the seal and the first reinforcement, and further ensuring the effective sealing of the seal.

[0028] In a possible design, the second reinforcement member is provided at the fixing portion.

[0029] In this design, it is stipulated that the second reinforcement is provided at the fixing part. Specifically, the second reinforcement is provided at the position where the fixing part is located, which can effectively improve the rigidity and strength of the position where the fixing part is located, and then when the seal is fixedly connected to the outer barrel of the clothing processing device through the fixing part, it is ensured that the fixing part and the outer barrel can be interference fit, thereby improving the connection effect between the seal and the outer barrel and further realizing effective sealing of the seal.

[0030] Among them, it should be noted that the second reinforcement can be made of metal skeleton material, and the metal skeleton material can be wrapped with rubber material, that is, the metal skeleton material is set in the seal. On the basis of improving the stiffness and strength of the position of the fixed part, it can ensure the connection effect between the seal and the second reinforcement, and further ensure the effective sealing of the seal.

[0031] In one possible design, the clothing processing device includes at least one guide post, and the seal further includes multiple connecting holes and at least one guide hole, wherein the multiple connecting holes are arranged on the fixing part, and the multiple connecting holes are used to fix the seal to the outer barrel, and at least one guide hole is arranged on the fixing part in a one-to-one correspondence with the guide post, and at least one guide hole is used to cooperate with at least one guide post.

[0032] In this design, the clothing processing device includes at least one guide post, which defines the seal as including multiple connection holes and at least one guide hole. Specifically, multiple connection holes are provided on the fixing portion, and the seal is fixedly connected to the outer barrel of the clothing processing device through the multiple connection holes. It is understood that the connection holes can be threaded holes, and the multiple threaded holes are evenly distributed. The seal is fixedly installed on the outer barrel of the clothing processing device by screws passing through the threaded holes, ensuring uniform force on all sides of the seal and further extending the service life of the seal. Furthermore, at least one guide hole is also provided on the fixing portion, and the guide holes are arranged one-to-one with the guide posts on the clothing processing device. Therefore, when the seal is installed on the outer barrel of the clothing processing device, the installation of the seal can be positioned and guided, thereby reducing the difficulty of seal installation and improving the efficiency of seal installation.

[0033] It should be noted that the number of guide holes can be multiple, which can further improve the installation efficiency of the clothing processing device. However, the number of guide holes should not be too large. If the number of guide holes is too large, multiple guide holes need to be aligned with multiple guide posts one by one for installation, which will increase the installation time of the seal and reduce installation efficiency. The specific number of connection holes and guide holes can be set according to actual needs.

[0034] According to a second aspect of the present invention, a clothes processing device is provided, comprising a seal provided by any of the above technical solutions, thereby having all the beneficial technical effects of the seal, which will not be described in detail here.

[0035] Furthermore, the clothing processing device also includes an inner barrel, an outer barrel, a clutch and a sealing disk, wherein the outer barrel is arranged on the outside of the inner barrel, the fixing part of the seal is fixedly installed on the outer barrel, the clutch is connected to the inner barrel, the clutch includes a dehydration shaft, the sealing disk is sleeved on the outside of the dehydration shaft, and the sealing part of the seal is sealed and connected to the sealing disk.

[0036] In this design, the clothing processing device is defined as also comprising an inner tub, an outer tub, a clutch, and a sealing disc. Specifically, the outer tub is sleeved on the outside of the inner tub, the fixed portion of the seal is fixedly connected to the outer tub, and the sealing disc is sleeved on the outside of the clutch dehydration shaft, so that the sealing portion of the seal and the sealing disc form a moving seal, thereby forming a seal between the inner tub and the clutch, and between the clutch and the outer tub, to prevent water leakage during operation of the clothing processing device. In addition, the transition portion within the seal allows relative movement between the fixed portion and the sealing portion in the radial and axial directions. Therefore, during operation of the clothing processing device, the relative movement generated by the transition portion can effectively offset the problem of misalignment between the seal and the sealing disc due to manufacturing precision and assembly tolerances, thereby effectively preventing deformation and wear of the seal during operation of the clothing processing device, which in turn reduces the service life of the seal, avoids water leakage during operation of the clothing processing device, and improves the user experience.

[0037] It should be noted that during the installation of the clothing processing device, the seal is first fixedly connected to the outer barrel, then the clutch is installed, and then the sealing disk is installed to form a seal between the sealing disk and the sealing part of the seal, and then the inner barrel and other components are installed to complete the installation process of the clothing processing device.

[0038] In addition, the clothes processing device provided by the above technical solution of the present invention also has the following additional technical features:

[0039] In a possible design, the clothing processing device further includes a mounting portion, which is disposed on a side of the outer tub facing the inner tub, and the sealing member is disposed on the mounting portion.

[0040] This design specifies that the clothing treatment device also includes a mounting portion. Specifically, a mounting portion is provided on the side of the outer tub facing the inner tub. The seal is mounted on the mounting portion and is securely connected to the outer tub via multiple connection holes. The provision of the mounting portion facilitates secure installation of the seal. It is understood that the structural compatibility of the mounting portion with the seal reduces the difficulty of seal installation and improves its efficiency.

[0041] In one possible design, the clothing processing device also includes a stop groove and a stop rib, wherein the stop groove is arranged on one of the stop part and the mounting part of the seal, and the stop rib and the stop groove are arranged on the other of the stop part and the mounting part of the seal in a one-to-one correspondence, and the stop rib can be inserted into the stop groove.

[0042] In this design, the clothing processing device is defined as further comprising a rotation-stop groove and a rotation-stop rib. Specifically, a rotation-stop groove is provided on one of the rotation-stop portion and the mounting portion of the seal, and a rotation-stop rib is provided on the other of the rotation-stop portion and the mounting portion. The rotation-stop rib can be inserted into the rotation-stop groove. Thus, through the position-limiting cooperation between the rotation-stop rib and the rotation-stop groove, the sealing portion of the seal can be prevented from rotating together with the inner drum, causing the seal to twist due to the fixed portion of the seal being stationary, thereby causing the seal to wear or even damage, thereby further extending the service life of the seal. Specifically, the rotation-stop groove can be provided on the rotation-stop portion and the rotation-stop rib can be provided on the mounting portion, or the rotation-stop rib can be provided on the rotation-stop portion and the rotation-stop groove can be provided on the mounting portion, and the specific arrangement can be determined according to actual needs. It is understood that multiple rotation-stop ribs and rotation-stop grooves can be provided in a one-to-one correspondence, and the rotation-stop ribs and rotation-stop grooves can be spaced apart along the circumferential direction of the seal to further ensure the limiting effect between the rotation-stop rib and the rotation-stop groove.

[0043] In addition, when a stop rib is provided on the mounting portion and a stop groove is provided on the stop portion, a drainage channel can be opened inside the stop rib to prevent water from accumulating between the outer barrel and the seal. The water can flow out to the drain port of the outer barrel through the drainage channel inside the stop rib, thereby preventing the problem of bacteria growing inside the clothing processing device due to long-term water accumulation between the outer barrel and the seal.

[0044] Among them, there is a clearance fit between the stop rib and the stop groove. On the basis of ensuring the limited fit between the stop rib and the stop groove, it can prevent the stop rib and the stop groove from causing wear between the stop rib and the inner wall of the stop groove when the inner barrel rotates at high speed due to interference fit, thereby further extending the service life of the seal.

[0045] In one possible design, the clothing processing device also includes a drain valve, a first drain outlet, a second drain outlet and a drainage channel, wherein the first drain outlet is arranged in the inner barrel and the second drain outlet is arranged in the outer barrel; the drainage channel is respectively connected to the drain valve, the first drain outlet and the second drain outlet.

[0046] In this design, it is defined that the clothing processing device also includes a drain valve, a first drain port, a second drain port and a drainage channel. Specifically, a first drain port is provided on the inner barrel, and a second drain port connected to the first drain port is provided on the outer barrel. The drainage channel is fixedly installed on the outer barrel. Specifically, the drainage channel is installed at the bottom of the outer barrel, and the drain valve is connected to the second drain port through the drainage channel. It can be understood that the drainage system of the clothing processing device is provided on the outer barrel, that is, the drainage system of the clothing processing device is separated from the clutch, and then an ordinary clutch can be installed on the clothing processing device to realize the washing and dehydration conditions of the clothing processing device.

[0047] Related art self-cleaning, single-tub pulsator washing machines utilize an intermediate drain clutch. This means the washing machine's drainage system is housed within the clutch, creating a drainage channel within the clutch, allowing water in the washing tub to drain through the clutch. However, this type of clutch is expensive compared to conventional clutches, hindering price competitiveness and hindering the promotion of single-tub pulsator washing machines. By separating the drainage system of the clothing processing device from the clutch, the need for an intermediate drain clutch is eliminated, allowing conventional clutches to replace the conventional intermediate drain clutches. This significantly reduces production costs and improves product competitiveness.

[0048] In one possible design, the clothing processing device also includes a tee and an air pressure sensor, the first port of the tee is connected to the drain valve, the second port of the tee is connected to the drain channel, and the air pressure sensor is connected to the third port of the tee.

[0049] In this design, the clothing treatment device is defined as also including a tee and an air pressure sensor. Specifically, the drain valve is connected to the first port of the tee, the drain channel is connected to the second port of the tee, and the air pressure sensor is connected to the third port of the tee. That is, the drain valve, the drain channel, and the air pressure sensor are connected through a tee. It can be understood that the air pressure sensor can detect the air pressure inside the clothing treatment device and can then determine the liquid level in the clothing treatment device based on the air pressure value. In other words, the liquid level in the clothing treatment device can be determined based on the detection result of the air pressure sensor, and the drain valve can be controlled based on the liquid level in the clothing treatment device, thereby improving the stability and reliability of the clothing treatment device during operation.

[0050] In one possible design, the clothing processing device also includes a first pipeline, a second pipeline, an air chamber and a third pipeline, wherein one end of the first pipeline is connected to the third port of the tee pipe, one end of the second pipeline is connected to the other end of the first pipeline, the air chamber is connected to the other end of the second pipeline, one end of the third pipeline is connected to the air chamber, and the other end of the third pipeline is connected to the air pressure sensor.

[0051] In this design, it is defined that the clothing processing device also includes a first pipeline, a second pipeline, an air chamber and a third pipeline. Specifically, one end of the first pipeline is connected to the third port of the tee pipe, one end of the second pipeline is connected to the other end of the first pipeline, the air chamber is connected to the other end of the second pipeline, one end of the third pipeline is connected to the air chamber, and the other end of the third pipeline is connected to the air pressure sensor. The connection between the drain valve, the drain channel and the air pressure sensor is achieved through the first pipeline, the second pipeline and the third pipeline, and the air chamber is set up to enable the air pressure sensor to detect the air pressure in the air chamber. The liquid level in the clothing processing device is judged by the detection result of the air pressure sensor, and the drain valve is controlled according to the liquid level in the clothing processing device, thereby improving the stability and reliability of the clothing processing device during operation.

[0052] In one possible design, the clothing processing device also includes a connecting plate, a sealing ring, a third drain outlet and a fourth drain outlet, wherein the clutch is connected to the inner barrel through the connecting plate, the sealing ring is arranged between the connecting plate and the sealing plate, the third drain outlet is arranged on the connecting plate, the third drain outlet is connected to the first drain outlet, the fourth drain outlet is arranged on the sealing ring, and the fourth drain outlet is respectively connected to the third drain outlet and the second drain outlet.

[0053] This design specifies that the clothing processing device also includes a connecting disc, a sealing ring, a third drain port, and a fourth drain port. Specifically, a sealing ring is disposed between the connecting disc and the sealing disc to enhance the sealing effect between the inner tub and the clutch. It is understood that the sealing ring can be configured as a composite gasket made of rubber-coated plastic with a metal frame, providing the sealing ring with a certain structural strength to ensure a good sealing effect. Furthermore, a retaining portion can be provided on the sealing ring, and a retaining hole can be provided on the dehydration shaft of the clutch. The retaining portion of the sealing ring can be snapped into the retaining hole of the dehydration shaft to prevent the sealing ring from being dislodged from the clothing processing device and causing water leakage.

[0054] Furthermore, a third drain outlet and a fourth drain outlet are respectively provided on the connecting plate and the sealing ring, the third drain outlet is connected to the first drain outlet, and the fourth drain outlet is respectively connected to the third drain outlet and the second drain outlet, so that the washing water can flow out from the first drain outlet, the third drain outlet, the fourth drain outlet, the second drain outlet, the drainage channel and the sealed channel of the drain valve, thereby realizing the separation of the drainage system of the clothing processing device from the clutch, so that the ordinary clutch can replace the intermediate drainage clutch in the related technology, thereby greatly reducing the production cost of the enterprise and improving the competitiveness of the product.

[0055] In addition, a sealing structure may be provided between the connecting plate and the inner barrel, and between the clutch and the outer barrel for sealing, so as to further ensure the sealing of the drainage system of the clothing processing device and enhance the user experience.

DETAILED DESCRIPTION

[0082] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0083] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0084] Refer to the following Figures 1 to 22 The sealing member 100 and the laundry treating apparatus according to some embodiments of the present invention will be described.

[0085] Example 1:

[0086] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, an embodiment of the first aspect of the present invention provides a seal 100 for a clothing processing device, the clothing processing device includes a sealing disk 240 and an outer barrel 220, and the seal 100 includes: a main body; a sealing portion 110, which is arranged on the main body, and the sealing portion 110 is used to be sealed and connected to the sealing disk 240; a fixing portion 120, which is arranged on the main body, and the fixing portion 120 is used to set the seal 100 on the outer barrel 220; a transition portion 130, which is arranged between the sealing portion 110 and the fixing portion 120, and the transition portion 130 can enable relative movement between the sealing portion 110 and the fixing portion 120.

[0087] The seal 100 provided in an embodiment of the present invention includes a main body, a sealing portion 110, a fixing portion 120 and a transition portion 130. Specifically, the sealing portion 110 is used to be sealed and connected to the sealing disk 240 of the clothing processing device. The seal 100 is fixedly installed on the outer barrel 220 of the clothing processing device through the fixing portion 120, so that the seal 100 can form a seal between the outer barrel 220 and the sealing disk 240. It can be understood that the sealing disk 240 is arranged between the inner barrel 210 and the clutch 230 of the clothing processing device, so that the seal 100 and the sealing disk 240 form a seal between the outer barrel 220 and the clutch 230, and between the inner barrel 210 and the clutch 230, thereby preventing water leakage and the like from occurring during the movement of the clothing processing device. Furthermore, a transition portion 130 is provided between the sealing portion 110 and the fixing portion 120. The transition portion 130 can cause relative movement between the sealing portion 110 and the fixing portion 120. That is, the transition portion 130 can cause relative movement between the fixing portion 120 and the sealing portion 110 in the radial and axial directions. Therefore, during the operation of the clothing processing device, the relative movement generated by the transition portion 130 can effectively offset the problem of the seal 100 and the sealing disk 240 being out of alignment due to manufacturing precision and assembly tolerance, thereby effectively preventing the seal 100 from being deformed and worn during the operation of the clothing processing device, thereby avoiding water leakage in the clothing processing device during operation and improving the user experience.

[0088] In addition, since vibrations are generated during the operation of the clothing processing device, the transition portion 130 can also offset the wear between the seal 100 and the sealing disk 240 caused by the vibrations generated during the operation of the clothing processing device, further extending the service life of the seal 100 and the sealing disk 240 of the clothing processing device, and thereby extending the service life of the clothing processing device.

[0089] It should be noted that the sealing portion 110, the fixing portion 120, and the transition portion 130 may be an integrated structure. This integrated structure has excellent mechanical properties, thereby ensuring the connection strength between the sealing portion 110, the transition portion 130, and the fixing portion 120, thereby ensuring the sealing effect of the seal 100. In addition, the integrated structure can also facilitate the processing and production of the seal 100, thereby reducing the service life of the seal 100.

[0090] It should also be noted that the seal 100 can be set to a rubber material. The hardness of the rubber material is relatively low, which can ensure the sealing effect of the seal 100. The rubber material has a certain degree of deformation, which can offset the problem of the seal 100 and the sealing disk 240 being out of alignment due to manufacturing precision and assembly tolerance, and thus can effectively prevent the seal 100 from deforming and wearing during the operation of the clothing processing device, thereby reducing the service life of the seal 100.

[0091] Example 2:

[0092] like Figure 1 and Figure 2 As shown, based on the above embodiment, the sealing portion 110 further includes at least one sealing lip and an elastic member 111, wherein the at least one sealing lip is used to be sealed and connected to the sealing disk 240, and the elastic member 111 is arranged on the side of the sealing portion 110 away from the at least one sealing lip.

[0093] In this embodiment, it is defined that the sealing portion 110 includes at least one sealing lip and an elastic member 111. Specifically, the seal 100 is sealed to the sealing disk 240 via at least one sealing lip. It can be understood that since the seal 100 is fixed on the outer barrel 220, the distance between the sealing portion 110 of the seal 100 and the sealing disk 240 is certain. By forming a moving seal between at least one sealing lip and the sealing disk 240, the contact area between the sealing portion 110 and the sealing disk 240 can be reduced, thereby increasing the mutual force between the sealing portion 110 and the sealing disk 240, improving the sealing effect between the seal 100 and the sealing disk 240, and further improving the sealing effect between the outer barrel 220 and the clutch 230, thereby further avoiding water leakage during the movement of the clothing processing device.

[0094] In addition, an elastic member 111 is provided on the side away from at least one sealing lip. Specifically, the elastic member 111 is sleeved on one of the at least one sealing lips, so that the elastic member 111 undergoes elastic deformation. When the elastic member 111 undergoes elastic deformation, a restoring force is generated. The restoring force makes one of the at least one sealing lips closer to the sealing disk 240, further improving the sealing effect between the seal 100 and the sealing disk 240.

[0095] It should be noted that the elastic member 111 may be a spring.

[0096] Example 3:

[0097] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, on the basis of the above embodiment, the clothing processing device further includes a mounting portion 250, and the seal 100 also includes a stop portion, which is arranged between the transition portion 130 and the sealing portion 110, and the stop portion is used to cooperate with the mounting portion 250 of the clothing processing device.

[0098] In this embodiment, the clothing processing device also includes a mounting portion 250, which limits the seal 100 to also include a stop portion. Specifically, a stop portion is further provided between the transition portion 130 and the sealing portion 110. The stop portion is used to cooperate with the mounting portion 250 of the clothing processing device, so that during the operation of the clothing processing device, the stop portion and a part of the mounting portion 250 can be limited to prevent the sealing portion 110 of the seal 100 from rotating together with the inner barrel 210, and the fixed portion 120 of the seal 100 does not move, causing the seal 100 to twist itself, resulting in wear of the seal 100 or even damage, thereby further extending the service life of the seal 100.

[0099] Example 4:

[0100] like Figure 2 As shown, based on the above embodiment, further, at least one sealing lip includes a first sealing lip 112 and a second sealing lip 113, wherein the second sealing lip 113 is arranged on a side of the first sealing lip 112 away from the rotation-stopping portion.

[0101] In this embodiment, at least one sealing lip is defined as including a first sealing lip 112 and a second sealing lip 113. Specifically, the second sealing lip 113 is disposed on a side of the first sealing lip 112 facing away from the anti-rotation portion, and the elastic member 111 is sleeved on the first sealing lip 112, thereby enabling a tight fit between the first sealing lip 112 and the sealing disk 240, thereby improving the sealing effect of the seal 100. Furthermore, the second sealing lip 113 is disposed on a side of the first sealing lip 112 facing away from the anti-rotation portion, i.e., the second sealing lip 113 is disposed above the first sealing lip 112, thereby forming a first sealing area between the first sealing lip 112 and the second sealing lip 113. It is understood that lubricating oil may be provided in the first sealing area to reduce wear between the sealing portion 110 of the seal 100 and the sealing disk 240 during operation of the laundry processing device, thereby extending the service life of the seal 100. By arranging the second sealing lip 113 above the first sealing lip 112, it is possible to prevent water, dust, hair, etc. from entering the position where the first sealing lip 112 is located from above, which may cause the sealing failure of the first sealing lip 112. In addition, by arranging the second sealing lip 113 above the first sealing lip 112, it is also possible to prevent the leakage of lubricating oil in the first sealing area between the first sealing lip 112 and the second sealing lip 113, which may cause wear of the sealing part 110 and the sealing disk 240, thereby further extending the service life of the seal 100.

[0102] like Figure 2 As shown, based on the above embodiment, further, at least one sealing lip further includes a third sealing lip 114 , and the third sealing lip 114 is arranged between the first sealing lip 112 and the second sealing lip 113 .

[0103] In this embodiment, the at least one sealing lip further includes a third sealing lip 114. Specifically, the third sealing lip 114 is provided between the first sealing lip 112 and the second sealing lip 113. This further prevents water, dust, or lint from entering the area where the first sealing lip 112 is located, which could cause sealing failure of the first sealing lip 112. Furthermore, this further prevents lubricant leakage from causing wear between the sealing portion 110 and the sealing disk 240, thereby extending the service life of the seal 100 and further ensuring the sealing effectiveness of the seal 100.

[0104] It can be understood that the second sealing lip 113 is close to the side of the inner barrel 210, and thus during the operation of the clothing processing device, it is easy for water, dust or hair to enter the first sealing lip 112 from above. Therefore, by arranging the third sealing lip 114 between the first sealing lip 112 and the second sealing lip 113, the sealing effect of the seal 100 can be further guaranteed.

[0105] like Figure 2 As shown, based on the above embodiment, further, at least one sealing lip further includes a fourth sealing lip 115, and the fourth sealing lip 115 is arranged on a side of the first sealing lip 112 close to the anti-rotation portion.

[0106] In this embodiment, the at least one sealing lip further includes a fourth sealing lip 115. Specifically, the fourth sealing lip 115 is provided on a side proximal to the rotation stop, i.e., the fourth sealing lip 115 is provided below the first sealing lip 112, thereby forming a second sealing region between the first sealing lip 112 and the fourth sealing lip 115. It is understood that lubricating oil may be provided in the second sealing region to further reduce wear between the sealing portion 110 and the sealing disk 240 of the seal 100 during operation of the laundry processing device, thereby extending the service life of the seal 100. Providing the fourth sealing lip 115 below the first sealing lip 112 prevents water, dust, or lint from entering the first sealing lip 112 from below, potentially causing sealing failure of the first sealing lip 112. Furthermore, providing the fourth sealing lip 115 below the first sealing lip 112 prevents lubricating oil from leaking from the second sealing region between the first and fourth sealing lips 112, potentially causing wear between the sealing portion 110 and the sealing disk 240, thereby further extending the service life of the seal 100.

[0107] Embodiment 5:

[0108] like Figure 1 and Figure 2 As shown, based on the above embodiment, the sealing member 100 further includes a first reinforcement member 140 , and the first reinforcement member 140 is disposed on the body close to the sealing portion 110 .

[0109] In this embodiment, it is defined that the seal 100 also includes a first reinforcement 140. Specifically, the first reinforcement 140 is provided at a position of the main body near the sealing portion 110, that is, the first reinforcement 140 is provided at a position of the main body near the sealing portion 110, which can enhance the rigidity, strength and roundness of the position where the sealing portion 110 is located. Since during the operation of the clothing processing device, the inner barrel 210 of the clothing processing device will rotate at high speed for washing or dehydration, by providing the first reinforcement 140 at a position close to the sealing portion 110, the structural strength at this position can be improved, thereby preventing the seal 100 from twisting during the high-speed rotation of the inner barrel 210, which may cause the sealing failure of the seal 100, thereby further extending the service life of the seal 100.

[0110] Among them, it should be noted that the first reinforcement 140 can be made of metal skeleton material, and the metal skeleton material is wrapped with rubber material, that is, the metal skeleton material is set in the seal 100. It can improve the stiffness, strength and roundness of the sealing part 110. On the basis of ensuring the connection effect between the seal 100 and the first reinforcement 140, further ensure the effective sealing of the seal 100.

[0111] like Figure 1 and Figure 2 As shown, based on the above embodiment, further, a second reinforcement member 150 is provided on the fixing portion 120 .

[0112] In this embodiment, it is defined that the second reinforcement 150 is provided at the fixing portion 120. Specifically, the second reinforcement 150 is provided at the position where the fixing portion 120 is located, which can effectively improve the rigidity and strength of the position where the fixing portion 120 is located, and then when the seal 100 is fixedly connected to the outer barrel 220 of the clothing processing device through the fixing portion 120, it is ensured that the fixing portion 120 and the outer barrel 220 can be interference fit, thereby improving the connection effect between the seal 100 and the outer barrel 220, and further realizing effective sealing of the seal 100.

[0113] Among them, it should be noted that the second reinforcement 150 can be made of metal skeleton material, and the metal skeleton material is coated with rubber material, that is, the metal skeleton material is set in the seal 100. It can improve the rigidity and strength of the position of the fixing part 120, while ensuring the connection effect between the seal 100 and the second reinforcement 150, and further ensure the effective sealing of the seal 100.

[0114] Example 6:

[0115] like Figure 3 and Figure 4 As shown, on the basis of the above embodiment, further, the clothing processing device includes at least one guide column, and the seal 100 also includes a plurality of connecting holes 160 and at least one guide hole 170, wherein the plurality of connecting holes 160 are arranged on the fixing portion 120, and the plurality of connecting holes 160 are used to fix the seal 100 to the outer barrel 220, and at least one guide hole 170 is arranged on the fixing portion 120 in a one-to-one correspondence with the guide column, and at least one guide hole 170 is used to cooperate with at least one guide column.

[0116] In this embodiment, the laundry processing device includes at least one guide post, which defines that the seal 100 also includes multiple connection holes 160 and at least one guide hole 170. Specifically, multiple connection holes 160 are provided on the fixing portion 120, through which the seal 100 is fixedly connected to the outer tub 220 of the laundry processing device. It is understood that the connection holes 160 may be threaded holes, with multiple threaded holes evenly distributed. Screws are passed through the threaded holes to secure the seal 100 to the outer tub 220 of the laundry processing device, ensuring uniform force on all sides of the seal 100 and further extending the service life of the seal 100. Furthermore, at least one guide hole 170 is also provided on the fixing portion 120. The guide holes 170 are arranged one-to-one with the guide posts on the laundry processing device. This allows for positioning and guiding the seal 100 when it is installed in the outer tub 220 of the laundry processing device, thereby reducing the difficulty of installing the seal 100 and improving the efficiency of the seal 100.

[0117] It should be noted that the number of guide holes 170 can be set to multiple, which can further improve the installation efficiency of the clothing processing device. However, the number of guide holes 170 should not be too large. If the number of guide holes 170 is too large, multiple guide holes 170 need to be aligned with multiple guide posts one by one for installation, which will increase the installation time of the seal 100 and reduce installation efficiency. The specific number of connecting holes 160 and guide holes 170 can be set according to actual needs.

[0121] In this embodiment, it is defined that the clothing processing device also includes an inner barrel 210, an outer barrel 220, a clutch 230 and a sealing disk 240. Specifically, the outer barrel 220 is sleeved on the outside of the inner barrel 210, the fixing portion 120 of the seal 100 is fixedly connected to the outer barrel 220, and the sealing disk 240 is sleeved on the outside of the dehydration shaft of the clutch 230, so that the sealing portion 110 of the seal 100 and the sealing disk 240 form a moving seal, and then form a seal between the inner barrel 210 and the clutch 230, and between the clutch 230 and the outer barrel 220, to prevent water leakage during operation of the clothing processing device. In addition, through the transition portion 130 in the seal 100, the fixing portion 120 and the sealing portion 110 can move relative to each other in the radial and axial directions. Therefore, during the operation of the clothing processing device, the relative movement generated by the transition portion 130 can effectively offset the problem of the seal 100 and the sealing disk 240 being out of alignment due to manufacturing precision and assembly tolerance, thereby effectively preventing the seal 100 from being deformed and worn during the operation of the clothing processing device, thereby reducing the service life of the seal 100, avoiding water leakage in the clothing processing device during operation, and improving the user experience.

[0122] It should be noted that during the installation of the clothing processing device, the seal 100 is first fixedly connected to the outer barrel 220, then the clutch 230 is installed, and then the sealing disk 240 is installed to form a seal between the sealing disk 240 and the sealing portion 110 of the seal 100, and then the inner barrel 210 and other components are installed to complete the installation process of the clothing processing device.

[0123] like Figure 15 、 Figure 16、 Figure 17 and Figure 18 As shown, based on the above embodiment, the clothing processing device further includes a mounting portion 250 , which is arranged on a side of the outer tub 220 facing the inner tub 210 , and the sealing member 100 is arranged on the mounting portion 250 .

[0124] In this embodiment, the clothing processing apparatus is further defined as comprising a mounting portion 250. Specifically, a mounting portion 250 is further provided on the side of the outer tub 220 facing the inner tub 210. The sealing member 100 is disposed on the mounting portion 250 and is fixedly connected to the outer tub 220 via a plurality of connection holes 160. The provision of the mounting portion 250 facilitates the fixed installation of the sealing member 100. It is understood that the mounting portion 250 is compatible with the structure of the sealing member 100, which can reduce the difficulty of installing the sealing member 100 and improve the installation efficiency of the sealing member 100.

[0125] Embodiment 8:

[0126] like Figure 5 、 Figure 16 and Figure 17 As shown, on the basis of the above embodiment, the clothing processing device further includes a stop groove 270 and a stop rib 260, wherein the stop groove 270 is arranged on one of the stop part and the mounting part 250 of the seal 100, and the stop rib 260 and the stop groove 270 are arranged on the other of the stop part and the mounting part 250 of the seal 100 in a one-to-one correspondence, and the stop rib 260 can be inserted into the stop groove 270.

[0127] In this embodiment, the laundry processing device further includes a rotation-stop groove 270 and a rotation-stop rib 260. Specifically, the rotation-stop groove 270 is provided on one of the rotation-stop portion and the mounting portion 250 of the seal 100, and the rotation-stop rib 260 is provided on the other of the rotation-stop portion and the mounting portion 250. The rotation-stop rib 260 can be inserted into the rotation-stop groove 270. Thus, the rotation-stop rib 260 and the rotation-stop groove 270 cooperate to prevent the sealing portion 110 of the seal 100 from rotating together with the inner tub 210. This would prevent the fixing portion 120 of the seal 100 from being stationary, causing the seal 100 to twist and wear or even damage the seal 100, thereby further extending the service life of the seal 100. Specifically, the rotation-stop groove 270 can be provided on the rotation-stop portion and the rotation-stop rib 260 can be provided on the mounting portion 250, or the rotation-stop rib 260 can be provided on the rotation-stop portion and the rotation-stop groove 270 can be provided on the mounting portion 250. The specific arrangement can be determined according to actual needs. It can be understood that a plurality of anti-rotation ribs 260 and anti-rotation grooves 270 can be provided in a one-to-one correspondence, and the anti-rotation ribs 260 and anti-rotation grooves 270 are arranged at intervals along the circumferential direction of the seal 100 to further ensure the limiting effect between the anti-rotation ribs 260 and the anti-rotation grooves 270.

[0128] In addition, when a stop rib 260 is provided on the mounting portion 250 and a stop groove 270 is provided on the stop portion, a drainage channel can be opened inside the stop rib 260 to prevent water from accumulating between the outer barrel 220 and the seal 100. Water can flow out to the drain outlet of the outer barrel 220 through the drainage channel inside the stop rib 260, thereby preventing the problem of bacteria growing inside the clothing processing device due to long-term water accumulation between the outer barrel 220 and the seal 100.

[0129] Among them, there is a clearance fit between the stop rib 260 and the stop groove 270. On the basis of ensuring the limited fit between the stop rib 260 and the stop groove 270, it can prevent the stop rib 260 and the stop groove 270 from causing wear between the stop rib 260 and the inner wall of the stop groove 270 when the inner barrel 210 rotates at high speed due to interference fit, thereby further extending the service life of the seal 100.

[0130] Embodiment 9:

Specifically, the drain channel 290 is installed at the bottom of the outer barrel 220, and the drain valve 280 is connected to the second drain port through the drain channel 290. It can be understood that the drainage system of the clothing processing device is provided on the outer barrel 220, that is, the drainage system of the clothing processing device is separated from the clutch 230, and then an ordinary clutch 230 can be installed on the clothing processing device to realize the washing and dehydration conditions of the clothing processing device.

[0133] Related art self-cleaning, single-tub pulsator washing machines utilize an intermediate drain clutch. This means the washing machine's drainage system is housed within the clutch, creating a drainage channel within the clutch, allowing water in the washing tub to drain through the clutch. However, this type of clutch is expensive compared to conventional clutches, hindering price competitiveness and hindering the promotion of single-tub pulsator washing machines. By separating the drainage system of the clothing processing device from the clutch, the need for an intermediate drain clutch is eliminated, allowing conventional clutches to replace the conventional intermediate drain clutches. This significantly reduces production costs and improves product competitiveness.

That is, the drain valve 280, the drain channel 290, and the air pressure sensor are connected via the tee 300. It is understood that the air pressure sensor can detect the air pressure inside the laundry processing device and can then determine the liquid level within the laundry processing device based on the air pressure value. In other words, the liquid level within the laundry processing device can be determined based on the detection result of the air pressure sensor, and the drain valve 280 can be controlled based on the liquid level within the laundry processing device, thereby improving the stability and reliability of the laundry processing device during operation.

[0136] In a specific embodiment, the clothing processing device further includes a first pipeline, a second pipeline, an air chamber and a third pipeline, wherein one end of the first pipeline is connected to the third port of the tee pipe 300, one end of the second pipeline is connected to the other end of the first pipeline, the air chamber is connected to the other end of the second pipeline, one end of the third pipeline is connected to the air chamber, and the other end of the third pipeline is connected to the air pressure sensor.

[0139] In this embodiment, the clothing processing device is further defined as comprising a connecting disc 310, a sealing ring 320, a third drain outlet, and a fourth drain outlet. Specifically, a sealing ring 320 is disposed between the connecting disc 310 and the sealing disc 240 to enhance the sealing effect between the inner tub 210 and the clutch 230. It is understood that the sealing ring 320 can be configured as a composite gasket of a rubber-coated metal frame material, providing the sealing ring 320 with a certain structural strength, thereby ensuring a good sealing effect. Furthermore, a retaining portion can be provided on the sealing ring 320, and a retaining hole can be provided on the dehydration shaft of the clutch 230. The retaining portion of the sealing ring 320 is engaged with the retaining hole of the dehydration shaft, thereby preventing the sealing ring 320 from being dislodged from the clothing processing device and causing water leakage.

[0140] Furthermore, a third drain outlet and a fourth drain outlet are respectively provided on the connecting plate 310 and the sealing ring 320. The third drain outlet is connected to the first drain outlet, and the fourth drain outlet is connected to the third drain outlet and the second drain outlet respectively, so that the washing water can flow out from the first drain outlet, the third drain outlet, the fourth drain outlet, the second drain outlet, the drainage channel 290 and the sealed channel of the drain valve 280, thereby realizing the separation of the drainage system of the clothing processing device from the clutch 230, so that the ordinary clutch 230 can replace the intermediate drainage clutch 230 in the related technology, thereby greatly reducing the production cost of the enterprise and improving the competitiveness of the product.

[0141] In addition, a sealing structure may be provided between the connecting disc 310 and the inner tub 210 and between the clutch 230 and the outer tub 220 for sealing, so as to further ensure the sealing of the drainage system of the clothing processing device and enhance the user experience.
