Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a clothing processing device. Background Technology

[0002] In laundry equipment such as drum washing machines, the bearing housing is located at the bottom of the outer drum to support the rotating shaft on the inner drum, which in turn drives the inner drum to rotate. During the operation of the washing machine, the laundry is prone to uneven distribution. The rotation of the inner drum generates a large centrifugal force, which can cause the inner drum to wobble and rub against itself. The bearing housing is also prone to deformation or breakage due to uneven stress. The low structural strength of the bearing housing cannot meet the normal operating requirements of the washing machine. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a garment processing device.

[0004] This application provides a garment processing device, comprising:

[0005] The bearing housing includes a split bearing base and a reinforcing plate. The bearing base has bearing mounting holes for mounting bearings. The reinforcing plate surrounds the bearing base and is fixedly connected to the bearing base.

[0006] The outer cylinder has the bearing seat embedded in the bottom of the outer cylinder, and the reinforcing plate extends radially along the outer cylinder, with the ratio of the outer diameter of the reinforcing plate to the diameter of the outer cylinder being greater than or equal to 0.25 and less than or equal to 1.0.

[0007] An inner cylinder is disposed inside the outer cylinder, and a rotating shaft is connected to the bottom of the inner cylinder. The rotating shaft is rotatably supported on the bearing seat through the bearing.

[0008] The garment processing equipment provided in this application includes a bearing housing, an outer cylinder, and an inner cylinder. The reinforcing plate and the bearing housing are separate structures. The bearing housing is used to install the bearing and support the rotation of the inner cylinder's rotating shaft. After the bearing housing and the reinforcing plate are fixedly connected, they are embedded in the bottom of the outer cylinder. The bearing housing is fixed relative to the outer cylinder, thereby supporting the inner cylinder and the rotation of the rotating shaft on the inner cylinder relative to the outer cylinder. Because the reinforcing plate and the bearing housing are separate structures, the reinforcing plate can be made of a higher-strength material. Compared with a one-piece bearing housing made of the same material, the overall structural strength of the bearing housing is effectively improved, which can prevent the inner cylinder from shaking or rubbing against the cylinder. This design improves the performance of garment processing equipment while reducing the material cost of integrated bearing housings. The ratio of the outer diameter of the reinforcing plate to the diameter of the outer cylinder is greater than or equal to 0.25 and less than or equal to 1.0. That is, the outer diameter of the reinforcing plate can be the same as the diameter of the outer cylinder at most, and at least 0.25 times the diameter of the outer cylinder. The reinforcing plate has sufficient dimensions in the radial direction along the outer cylinder to ensure that the reinforcing plate itself has high structural strength, thereby better improving the overall structural strength of the bearing housing. At the same time, the force on the reinforcing plate can be evenly transmitted radially to the bottom of the outer cylinder to avoid stress concentration on the outer cylinder, reduce vibration, and extend service life.

[0009] In some embodiments, the material strength of the reinforcing plate is greater than the material strength of the bearing base.

[0010] In some embodiments, the bearing base is a cast iron structural component or a cast aluminum structural component, and the reinforcing plate is a plastic component or a galvanized steel component.

[0011] In some embodiments, the reinforcing plate is an annular structure with a central through hole formed on it for the bearing base portion to pass through, and the ratio of the inner diameter to the outer diameter of the reinforcing plate is greater than or equal to 0.25 and less than 1.0.

[0012] In some embodiments, a connecting plate is provided on the outer peripheral surface of the bearing base along the circumferential direction, and the reinforcing plate overlaps and is fixedly connected to the connecting plate.

[0013] In some embodiments, the reinforcing plate has an overlapping portion that overlaps with the connecting plate. The connecting plate has a connecting hole. A connecting post is formed in the area of ​​the overlapping portion corresponding to the connecting hole. The connecting post passes through the connecting hole. A limiting portion is formed at one end of the connecting post away from the overlapping portion. The connecting plate is limited between the overlapping portion and the limiting portion.

[0014] In some embodiments, the area on the overlapping portion corresponding to the connecting hole is stamped to form the connecting post in the direction toward the connecting hole, and the connecting post extends beyond the connecting plate away from the overlapping portion, and the portion of the connecting post extending beyond the connecting plate is riveted to form the limiting portion.

[0015] In some embodiments, the reinforcing plate has a plurality of through holes, and the through holes are filled with the same injection molding material as the material used for injection molding the outer cylinder.

[0016] In some embodiments, a plurality of deformable portions are formed by stamping on the reinforcing plate, and a stamping cut is formed between the deformable portions and the reinforcing plate.

[0017] In some embodiments, a plurality of the deformable portions are arranged circumferentially along the reinforcing plate, and each of the deformable portions extends radially along the reinforcing plate. Attached Figure Description

[0027] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0029] The garment processing equipment will be described in detail below through specific embodiments:

[0030] Reference Figures 1 to 6 As shown, some embodiments of the present invention provide a garment processing device, including a bearing housing 1, an outer cylinder 2, and an inner cylinder 3.

[0031] The bearing housing 1 includes a split bearing base 11 and a reinforcing plate 12. The bearing base 11 has a bearing mounting hole 111 for mounting the bearing 4. The inner cylinder 3 is placed inside the outer cylinder 2. The bottom of the inner cylinder 3 is connected to a rotating shaft 31. The rotating shaft 31 is rotatably supported on the bearing housing 1 by the bearing 4. That is to say, the bearing base 11 can support the bearing 4 and bear the force caused by the unbalanced centrifugal force on the rotating shaft 31.

[0032] The reinforcing plate 12 surrounds the bearing base 11 and is fixedly connected to the bearing base 11; the bearing seat 1 is embedded in the bottom of the outer cylinder 2; the reinforcing plate 12 extends radially along the outer cylinder 2; and the ratio of the outer diameter of the reinforcing plate 12 to the diameter of the outer cylinder 2 is greater than or equal to 0.25 and less than or equal to 1.0.

[0033] In practice, the reinforcing plate 12 and the bearing base 11 are separate structures. The bearing base 11 is used to install the bearing 4 and support the rotation shaft 31 of the inner cylinder 3 to rotate through the bearing 4. After the bearing base 11 and the reinforcing plate 12 are fixedly connected, they are embedded in the bottom of the outer cylinder 2. The bearing seat 1 is fixed relative to the outer cylinder 2, thereby supporting the inner cylinder 3 and the rotation shaft 31 on the inner cylinder 3 to rotate relative to the outer cylinder 2. Since the reinforcing plate 12 and the bearing base 11 are separate structures, the reinforcing plate 12 can be made of a higher strength material. Compared with the one-piece bearing seat 1 made of the same material, the overall structural strength of the bearing seat 1 is effectively improved, which can avoid the inner cylinder 3 from shaking or rubbing, and can improve the product performance of the garment processing equipment.

[0034] Furthermore, the ratio of the outer diameter of the reinforcing plate 12 to the diameter of the outer cylinder 2 is greater than or equal to 0.25 and less than or equal to 1.0. That is, the outer diameter of the reinforcing plate 12 can be the same as the diameter of the outer cylinder 2 at most, and at least 0.25 times the diameter of the outer cylinder 2. The reinforcing plate 12 has sufficient dimensions in the radial direction along the outer cylinder 2 to ensure that the reinforcing plate 12 itself has high structural strength, thereby better improving the overall structural strength of the bearing seat 1. At the same time, the force on the reinforcing plate 12 can also be evenly transmitted to the bottom of the outer cylinder 2 in the radial direction to avoid the force concentration on the outer cylinder 2, thereby reducing vibration and extending service life.

[0035] Specifically, the outer diameter of the reinforcing plate 12 can be 0.25 times, 0.35 times, 0.5 times, or 0.75 times the diameter of the outer cylinder 2, or the same as the diameter of the outer cylinder 2. In the case of limited installation space, the bearing seat 1 can ensure greater structural strength to meet greater usage requirements. The structure is simple and easy to process.

[0036] Specifically, the bearing housing 1 can be connected to the bottom of the outer cylinder 2 during injection molding to ensure the stability of the connection between the two, so that the force on the bearing housing 1 can be evenly transmitted to the bottom of the outer cylinder 2, avoiding the outer cylinder 2 from cracking due to stress concentration.

[0037] The outer drum 2 is equipped with a drive motor and a transmission mechanism. The drive motor is connected to the transmission mechanism, which is connected to the rotating shaft 31 on the inner drum 3. The drive motor and transmission mechanism drive the rotating shaft 31 to rotate, thereby causing the inner drum 3 to rotate to achieve washing. Specifically, the transmission mechanism can drive the rotating shaft 31 through belt drive, gear drive, or chain drive.

[0038] In some embodiments, the material strength of the reinforcing plate 12 is greater than that of the bearing base 11. It is understood that, given that the material strength of the bearing base 11 is sufficient to support the operation of the bearing 4, selecting a stronger material for the reinforcing plate 12 can increase its structural strength independently. With the same outer diameter of the bearing housing 1, the reinforcing plate 12 can further increase the structural strength of the bearing housing 1. In other words, with a fixed outer cylinder 2 size or limited installation space, the bearing housing 1 can maintain structural strength and meet usage requirements while controlling costs.

[0039] In practice, the bearing base 11 is a cast iron or cast aluminum structural component. It is understood that both cast iron and cast aluminum components possess sufficient structural strength to support the bearing 4, preventing damage caused by excessive unbalanced centrifugal force from the rotating shaft 31 and ensuring its service life. Specifically, the bearing base 11 can be manufactured by casting or die casting of aluminum.

[0040] Of course, it should be noted that the bearing base 11 can also be a structural component made of other materials. This application does not limit this, as long as it can support the bearing 4 and has a certain structural strength to overcome the unbalanced centrifugal force from the inner cylinder 3 and the rotating shaft 31.

[0041] Furthermore, the reinforcing plate 12 is made of plastic or galvanized steel. Specifically, the plastic part is a high-strength plastic part. Both high-strength plastic parts and galvanized steel parts have high structural strength, and their material strength is higher than that of the bearing base 11, such as cast iron or cast aluminum structural parts. This arrangement can improve the overall structural strength of the bearing base 1.

[0042] Of course, it should be noted that the reinforcing plate 12 can also be a structural component made of other materials. This application does not limit this, as long as the material strength is higher than that of the bearing base 11, so as to achieve the purpose of controlling costs while improving the overall strength of the bearing base 1.

[0043] In some embodiments, the reinforcing plate 12 is an annular structure with a central through hole 121 formed on it for the bearing base 11 to pass through. The bearing base 11 passes through the central through hole 121. The reinforcing plate 12 surrounds the outer periphery of the bearing base 11 and can be fixedly connected to the bearing base 11. After the reinforcing plate 12 and the bearing base 11 are connected, they can be embedded in the bottom of the outer cylinder 2 to complete the connection between the bearing seat 1 and the outer cylinder 2.

[0044] Reference Figure 2 and Figure 6As shown, the reinforcing plate 12 is a plate-shaped structure. The annular plate-shaped structure is integrally embedded in the bottom of the outer cylinder 2. The reinforcing plate 12 and the bottom of the outer cylinder 2 can be evenly stressed, thus extending the service life.

[0045] In practice, the ratio of the inner diameter to the outer diameter of the reinforcing plate 12 is greater than or equal to 0.25 and less than 1.0. That is, the inner diameter of the reinforcing plate 12 is smaller than its outer diameter, and the minimum inner diameter of the reinforcing plate 12 is 0.25 times its outer diameter. Specifically, the inner diameter of the reinforcing plate 12 can be 0.25 times, 0.35 times, or 0.5 times its outer diameter, and can be set according to actual needs.

[0046] It is understandable that the bearing base 11 has a certain size to ensure that the bearing base 11 has the structural strength to support the bearing 4, the inner diameter of the reinforcing plate 12 is greater than or equal to 0.25 times the outer diameter of the reinforcing plate 12, and it can also ensure that a sufficiently large central through hole 121 is formed in the middle of the reinforcing plate 12 so that the bearing base 11 can pass through, thereby completing the connection between the bearing base 11 and the reinforcing plate 12.

[0047] In some embodiments, refer to Figure 2 and Figure 3 As shown, a connecting plate 112 extends circumferentially on the outer circumferential surface of the bearing base 11. That is, the connecting plate 112 is formed into a ring plate structure, and the reinforcing plate 12 and the connecting plate 112 can overlap and be fixedly connected to each other. In specific implementation, the connecting plate 112 and the bearing base 11 can be formed into an integral structure by casting or die casting, which can ensure high structural strength.

[0048] It is understandable that the reinforcing plate 12 and the connecting plate 112 overlap each other and have a certain overlapping part. The overlapping part is also a ring structure. After the reinforcing plate 12 and the connecting plate 112 overlap each other and are fixed, the overlapping part can be subjected to uniform force, avoiding the problem of stress concentration and local fracture.

[0049] It should be noted that the inner diameter of the reinforcing plate 12 is at least 0.25 times greater than or equal to the outer diameter of the reinforcing plate 12, so as to ensure that the bearing base 11 can be inserted into the central through hole 121 of the reinforcing plate 12. Furthermore, the outer diameter of the connecting plate 112 must be greater than the inner diameter of the reinforcing plate 12, so that the reinforcing plate 12 and the connecting plate 112 can overlap and be fixed together, thereby fixing the reinforcing plate 12 and the bearing base 11 together.

[0050] In some embodiments, refer to Figure 4As shown, the reinforcing plate 12 has an overlapping portion 122 that overlaps with the connecting plate 112. That is, the overlapping portion of the reinforcing plate 12 and the connecting plate 112 is formed as the overlapping portion 122. The connecting plate 112 has a connecting hole 113. A connecting post 123 is formed in the area of ​​the overlapping portion 122 corresponding to the connecting hole 113. The connecting post 123 passes through the connecting hole 113. A limiting portion 124 is formed at the end of the connecting post 123 away from the overlapping portion 122. The connecting plate 112 is limited between the overlapping portion 122 and the limiting portion 124.

[0051] In other words, the connecting post 123 is provided on the overlapping portion 122 of the reinforcing plate 12. After passing through the connecting hole 113 on the connecting plate 112, the limiting portion 124 provided at the end of the connecting post 123 away from the overlapping portion 122 can limit the connecting plate 112 between the overlapping portion 122 and the limiting portion 124, thereby completing the connection between the overlapping portion 122 and the connecting plate 112, and thus realizing the fixed connection between the reinforcing plate 12 and the bearing base 11.

[0052] In specific implementation, the area on the overlapping part 122 corresponding to the connecting hole 113 is stamped to form the connecting post 123 in the direction toward the connecting hole 113. It can be understood that the connecting post 123 is directly formed by stamping the area on the overlapping part 122 corresponding to the connecting hole 113. That is, the connecting post 123 and the overlapping part 122 are an integral structure. This can prevent the connecting post 123 from detaching from the overlapping part 122 of the reinforcing plate 12 when the outer cylinder 2 or the bearing seat 1 vibrates due to the centrifugal force of the inner cylinder 3 or the rotating shaft 31. This can ensure the connection stability between the reinforcing plate 12 and the bearing base 11.

[0053] The connecting post 123 extends beyond the connecting plate 112 away from the overlapping portion 122, and the portion of the connecting post 123 extending beyond the connecting plate 112 is riveted to form a limiting portion 124. In other words, the portion of the connecting post 123 extending beyond the connecting plate 112 can form a limiting portion 124 after being riveted and deformed, and can then abut against the side of the connecting plate 112 away from the overlapping portion 122, thereby limiting the connecting plate 112 between the limiting portion 124 and the overlapping portion 122.

[0054] Specifically, the edge of the limiting part 124 extends beyond the edge of the connecting hole 113 on the connecting plate 112, which can prevent the limiting part 124 from detaching from the connecting hole 113 and causing the reinforcing plate 12 to detach from the bearing base 11, thereby ensuring that the reinforcing plate 12 and the bearing base 11 can be stably connected.

[0055] In specific implementation, refer to Figure 5As shown, the overlapping part 122 and the connecting plate 112 can be connected by the mold 5. The mold 5 includes an upper mold 51 and a lower mold 52. The upper mold 51 is provided with a stamping punch. During the process of the upper mold 51 moving toward the connecting plate 112, the stamping punch can cause the upper part of the overlapping part 122 to deform to form a connecting post 123. The connecting post 123 can pass through the connecting hole 113 and extend beyond the side surface of the connecting plate 112 away from the overlapping part 122 during the stamping process.

[0056] Furthermore, the lower mold 52 is provided with a groove structure. During the mold closing process where the upper mold 51 and the lower mold 52 gradually approach each other, the portion of the connecting post 123 that extends beyond the connecting plate 112 can undergo riveting deformation within the groove structure to form the limiting part 124. It can be understood that during one mold closing process of the upper mold 51 and the lower mold 52, the connecting post 123 and the limiting part 124 can be generated sequentially, thereby directly completing the connection between the overlapping part 122 and the connecting plate 112. This enables the fixed connection between the reinforcing plate 12 and the bearing base 11, simplifying and speeding up the process and improving production efficiency.

[0057] It should be noted that the overlapping part 122 and the connecting plate 112 can also be fixedly connected in other ways, such as by connecting parts such as screws or rivets. This application does not limit this, as long as the connecting parts such as screws or rivets can be fixedly set on the overlapping part 122 or the connecting plate 112, so as to avoid the problem of the reinforcing plate 12 detaching from the bearing base 11 due to vibration.

[0058] In some embodiments, refer to Figure 6 As shown, the reinforcing plate 12 has multiple through holes 125, which allow for smooth flow of injection molding material and facilitate molding. The through holes 125 are filled with the same injection molding material as the injection-molded outer cylinder 2. It can be understood that during the injection molding process of the outer cylinder 2, the injection molding material can fill the through holes 125 on the reinforcing plate 12. Furthermore, after the injection molding material solidifies, the limiting force between the injection molding material and the hole walls of the through holes 125 enhances the connection strength between the bottom of the outer cylinder 2 and the reinforcing plate 12.

[0059] Specifically, multiple through holes 125 are evenly distributed on the reinforcing plate 12, which makes the structural strength of the reinforcing plate 12 more uniform. Thus, when the reinforcing plate 12 is embedded in the inner cylinder 3, the centrifugal force on the bearing seat 1 is evenly distributed to the inner cylinder 3, thereby ensuring the structural strength of the product.

[0060] In some embodiments, continue to refer to Figure 6As shown, multiple deformable portions 126 are stamped on the reinforcing plate 12. By forming deformable portions 126 on the reinforcing plate 12, the structural strength of the reinforcing plate 12 can be increased, thereby increasing the overall structural strength of the bearing seat 1, avoiding the shaking or grinding problem of the inner cylinder 3, and improving the product performance of the garment processing equipment.

[0061] In practice, a stamping cut 127 is formed between the deformable part 126 and the reinforcing plate 12. The injection molding material can fill the stamping cut 127 between the deformable part 126 and the reinforcing plate 12, thereby improving the connection strength between the bottom of the outer cylinder 2 and the reinforcing plate 12.

[0062] Furthermore, multiple deformable portions 126 are spaced apart circumferentially along the reinforcing plate 12, and each deformable portion 126 extends radially along the reinforcing plate 12. This arrangement ensures that the structural strength of the reinforcing plate 12 is relatively uniform, thereby evenly distributing the centrifugal force on the bearing seat 1 to the inner cylinder 3 when the reinforcing plate 12 is embedded in the inner cylinder 3. Of course, the deformable portions 126 can also be of other shapes; this application does not limit this and allows for specific configuration according to actual needs.

[0063] It should be noted that the deformable part 126 can also be a closed structure formed by directly arching through stamping. This application does not limit this, as long as the reinforcing plate 12 and the deformable part 126 can be embedded in the bottom of the outer cylinder 2, and the injection molding material can fill the cavity structure formed by stamping on the reinforcing plate 12 to improve the connection strength between the bottom of the cylinder and the reinforcing plate 12.

[0064] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0065] The above are merely specific embodiments of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
