Detailed Implementation

[0026] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0027] Secondly, it should be noted that in the description of the embodiments of this application, the terms "inner" and "outer" and other terms indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the embodiments of this application.

[0028] Furthermore, it should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0029] In related technologies, drum washing machines have a window gasket at the front end of the outer drum. The gasket is sealed by the pressure of the door / window, preventing water from leaking out during washing. However, with use, this gasket is prone to damage, affecting the sealing effect. Researchers have found that in some drum washing machines, the inner drum opening is not concentric with the access panel on the front panel, with the access panel higher than the inner drum opening. To reduce the gap between the inner drum opening and the door / window, a design is often used where the front flange of the outer drum is raised, making it higher than the edge of the inner drum opening. The gasket, which mates with the front flange of the outer drum, is easily exposed to direct contact with the load, causing friction and leading to damage and compromised sealing.

[0030] Further research by the researchers revealed that existing window gaskets typically have an inner edge for fixed connection with the front flange at the front end of the outer drum. The inner edge is in direct contact with the washing load in the inner drum, resulting in high friction and easy damage to the window gasket.

[0031] In view of this, this application provides a new type of window gasket that fits onto the front side of the outer cylinder front flange and is provided with a snap-fit ​​structure for snap-fit ​​positioning with the outer cylinder front flange. In this way, while achieving a fixed connection between the window gasket and the outer cylinder front flange, the window gasket is located on the front side of the outer cylinder front flange, eliminating the inner edge design of the window gasket, avoiding contact with loads such as clothing inside the cylinder and thus avoiding friction, improving the service life of the window gasket, and ensuring the sealing effect of the window gasket.

[0032] The optional technical solutions of the window pad and roller-type clothing processing equipment of this application are described below with reference to the accompanying drawings.

[0033] First, it should be noted that in the embodiments of this application, the directional terms "front" refer to the side facing the door of the drum-type garment processing equipment, and "rear" refer to the side facing the bottom of the drum-type garment processing equipment; "inner" refers to the side facing the center of the window pad, and "outer" refers to the side away from the center of the window pad.

[0034] Figure 1 This is an exploded view of the front flange and window gasket of the outer drum of the roller-type garment processing device provided in the embodiments of this application.

[0035] This application provides a drum-type garment processing device, such as a drum-type washing machine, a drum-type dryer, or a drum-type washer-dryer combo.

[0036] Combination Figure 1 The roller-type garment processing device of this application includes a box, an outer cylinder, an inner cylinder, and a window pad 100.

[0037] The cabinet includes a front panel, a rear panel, a top panel, a bottom panel, and two side panels, which together form a rectangular shell to house other components of the drum-type garment processing equipment. The front panel has an access opening for loading and unloading laundry, blankets, and other washing loads. A door is also installed on the front panel, which can rotate relative to the cabinet to open or close the access opening. An observation window is provided on the door for easy monitoring of the washing process.

[0038] Both the inner and outer drums are installed inside the cabinet, and the inner drum is rotatably installed inside the outer drum. Under the action of the drive motor, the inner drum rotates relative to the outer drum to achieve washing and dehydration of clothes.

[0039] The outer cylinder is suspended and installed inside the enclosure by a suspension component, such as a hanging spring. The outer cylinder includes an outer cylinder body and an outer cylinder front flange 200, which is fixed to the front end of the outer cylinder body. The outer cylinder front flange 200 is connected to the front panel of the enclosure by an annular window gasket 100. The observation window extends into the circular space enclosed by the window gasket 100, and the observation window abuts against the window gasket 100 to provide a seal and prevent water leakage from the door.

[0040] Figure 2 This is a rear view of the window pad provided in an embodiment of this application; Figure 3 yes Figure 2 Sectional view along the BB direction; Figure 4 yes Figure 3 A magnified schematic diagram of the Q region.

[0041] Combination Figures 2 to 4 The window gasket 100 of this application embodiment includes: a window gasket body 110, a first connecting structure 120, and a second connecting structure 130. The first connecting structure 120 is disposed at the rear end of the window gasket body 110 and is used to connect with the front flange 200 of the outer cylinder; the second connecting structure 130 is disposed at the front end of the window gasket body 110 and is used to connect with the front panel.

[0042] Optionally, in this embodiment, the window gasket body 110, the first connecting structure 120, and the second connecting structure 130 are integrally formed, which helps to improve the structural strength and sealing performance of the window gasket.

[0043] Combination Figure 1 as well as Figure 2The first connecting structure 120 in this embodiment includes a first connecting wall 121 and a snap-fit ​​structure 122. The front end of the first connecting wall 121 is connected to the rear end of the window gasket body 110, and the first connecting wall 121 is fitted to the front side of the outer cylinder front flange 200, which can ensure the sealing of the connection and improve the reliability of the connection. By setting the first connecting wall 121, this embodiment allows the window gasket body 110 to have the same structure as the original, ensuring that the gap between the window gasket 100 and the outer cylinder front flange 200 is consistent with the original structure, which facilitates observation and cleaning.

[0044] A snap-fit ​​structure 122 is provided on the rear side of the first connecting wall 121. The snap-fit ​​structure 122 is snap-fitted and positioned with the outer cylinder front flange 200, thereby fixing the window gasket 100 to the outer cylinder front flange 200, which facilitates the cooperation between the window gasket 100 and other structures of the outer cylinder front flange 200.

[0045] Optionally, the snap-fit ​​structure 122 can be located at any position in the circumferential direction of the first connecting wall 121. For example, the snap-fit ​​structure 122 can be set at the top of the first connecting wall 121. In this embodiment, the snap-fit ​​structure 122 is set at the bottom of the first connecting wall 121. This setting allows it to snap onto the portion of the outer cylinder front flange 200 that extends upward, eliminating the need to additionally set a snap-fit ​​structure on the outer cylinder front flange 200.

[0046] The snap-fit ​​structure 122 can take various forms. For example, the snap-fit ​​structure 122 may include an arc-shaped connecting arm and a snap-fit ​​part disposed at the end of the arc-shaped connecting arm. Correspondingly, the outer cylinder front flange 200 is provided with a latch that engages with the snap-fit ​​part. By engaging the snap-fit ​​part with the latch, the snap-fit ​​structure 122 and the outer cylinder front flange 200 are snap-fit ​​positioned together. As another example, the snap-fit ​​structure 122 may include a boss disposed on the rear side of the first connecting wall 121, with a latch disposed on the boss. Correspondingly, the outer cylinder front flange 200 is provided with a snap-fit ​​protrusion that mates with the latch. By engaging the snap-fit ​​protrusion with the latch, the snap-fit ​​structure 122 and the outer cylinder front flange 200 are snap-fit ​​positioned together.

[0047] In this embodiment, the snap-fit ​​structure 122 includes a plurality of snap fasteners 1221, which are arranged at intervals along the circumference of the first connecting wall 121. Correspondingly, the outer cylinder front flange 200 is provided with a plurality of snap holes 221 for engaging with the snap fasteners 1221, the number of snap holes 221 being the same as the number of snap fasteners 1221. For example, the snap-fit ​​structure 122 includes four snap fasteners 1221 arranged at intervals along the circumference of the first connecting wall 121, and four snap holes 221 are provided, such that each snap fastener 1221 is engaged through one snap hole 221. By engaging with the snap fasteners 1221 through the snap holes 221, the snap-fit ​​structure 122 and the outer cylinder front flange 200 are engaged and positioned.

[0048] The snap-fit ​​structure 122 of this application embodiment, by setting multiple snap-fits 1221, not only helps to improve the stability of the window gasket 100 installation, but also facilitates the assembly of the window gasket 100 and the outer cylinder front flange 200.

[0049] In some embodiments, combined with Figure 2 Multiple snap fasteners 1221 are located at the bottom of the first connecting wall 121; the first connecting wall 121 has a vertical center line H, and the first connecting wall 121 is symmetrical about the vertical center line H; the multiple snap fasteners 1221 are symmetrical about the vertical center line H. This arrangement makes the snapping force between the snap fasteners 1221 on both sides of the vertical center line H and the outer cylinder front flange 200 balanced, avoiding the deformation of the window gasket 100 due to uneven force, thereby improving the sealing performance of the window gasket 100.

[0050] In some possible implementations, multiple snap fasteners 1221 are evenly spaced along the circumference of the first connecting wall 121, such that the circumferential spacing between two adjacent snap fasteners 1221 is the same; this facilitates the arrangement and processing of the snap fasteners 1221.

[0051] In some other possible implementations, the circumferential spacing between at least two adjacent snap fasteners 1221 is different from the circumferential spacing between other adjacent snap fasteners 1221. For example, when four snap fasteners 1221 are arranged circumferentially along the first connecting wall 121, the circumferential spacing between the two middle snap fasteners 1221 is smaller, and the circumferential spacing between the two edge snap fasteners 1221 and their adjacent snap fasteners 1221 is larger. This arrangement can ensure a stable connection between the bottom of the window gasket 100 where the gravity is concentrated and the front flange of the outer cylinder 200, and also has a larger circumferential snapping distance, which is beneficial to further improve the stability of the connection between the window gasket 100 and the front flange of the outer cylinder 200.

[0052] Combination Figure 3 and Figure 4 The buckle 1221 in this embodiment includes a connecting post 1222 and a snap-fit ​​connector 1223. The first end of the connecting post 1222 is connected to the rear side of the first connecting wall 121, and the second end of the connecting post 1222 is connected to the snap-fit ​​connector 1223. The cross-sectional area of ​​the snap-fit ​​connector 1223 is larger than the cross-sectional area of ​​the connecting post 1222, so that the snap-fit ​​connector 1223, the connecting post 1222, and the first connecting wall 121 form an annular groove.

[0053] The cross-sections of the snap connector 1223 and the connecting post 1222 are both formed by cutting with a plane perpendicular to the axial direction of the connecting post 1222.

[0054] Thus, the connecting column 1222 passes through the locking hole 221, and the locking connector 1223 passes through the locking hole 221 and engages with the outer cylinder front flange 200, so that the part of the outer cylinder front flange 200 around the locking hole 221 cooperates with the annular groove, thereby realizing the locking and fixing of the window gasket 100 and the outer cylinder front flange 200.

[0055] Typically, the window gasket 100 is a plastic part, such as a rubber part, which utilizes the elastic deformation of the snap fastener 1223 to allow the snap fastener 1223 to pass through the snap hole 221.

[0056] The snap-fit ​​connector 1223 can have various shapes, such as cuboid or cylinder. In this embodiment, the snap-fit ​​connector 1223 is frustoconical, and the larger end of the snap-fit ​​connector 1223 is connected to the connecting post 1222. This arrangement not only enables snap-fit ​​connection with the outer cylinder front flange 200, but also facilitates the snap-fit ​​connector 1223 passing through the snap-fit ​​hole 221, improving the ease of assembly.

[0057] Continue to refer to Figure 3 and Figure 4 The first connecting wall 121 in this embodiment includes a first inclined portion 1211, a first connecting portion 1212, a second connecting portion 1213, a third connecting portion 1214, and an extension portion 1215.

[0058] In this embodiment, the diameter of the front end of the first inclined portion 1211 is smaller than the diameter of the rear end of the first inclined portion 1211. The front end of the first inclined portion 1211 is connected to the rear end of the window gasket body 110, and a snap-fit ​​structure 122 is provided on the first inclined portion 1211.

[0059] The rear end of the first inclined portion 1211 bends backward and extends to form a first connecting portion 1212; the first connecting portion 1212 bends and extends toward the center of the window pad 100 to form a second connecting portion 1213; the second connecting portion 1213, the first connecting portion 1212 and the first inclined portion 1211 together enclose to form a first mating groove 1216; the first mating groove 1216 opens toward the center of the window pad 100.

[0060] The second connecting portion 1213 bends backward away from the first inclined portion 1211 to form the third connecting portion 1214. The third connecting portion 1214 bends backward away from the center of the window pad 100 to form the extension portion 1215. The extension portion 1215, the third connecting portion 1214 and the second connecting portion 1213 form the second mating protrusion 1217.

[0061] The first connecting wall 121 of this application embodiment forms a first mating groove 1216 and a second mating protrusion 1217, which mates with the outer cylinder front flange 200 to improve the stability and reliability of the connection between the window gasket 100 and the outer cylinder front flange 200.

[0062] The following is combined Figures 5 to 7 This describes the mating structure between the outer cylinder front flange 200 and the first connecting wall 121 in an embodiment of this application. Figure 5 This is a front view of the outer drum front flange and window gasket of the drum-type garment processing device provided in this application embodiment; Figure 6 yes Figure 5 Sectional view along the AA direction; Figure 7 yes Figure 6 A magnified schematic diagram of region P in the middle.

[0063] Combination Figure 6 and Figure 7 The outer cylinder front flange 200 of this application embodiment includes a flange body 210 and a fixing part 220. The rear end of the flange body 210 is used to be fixedly connected to the outer cylinder body; the front end of the flange body 210 is fixedly connected to the fixing part 220, and the fixing part 220 is provided with a locking hole 221 for connecting to the window gasket 100.

[0064] The fixing part 220 includes a fixing wall 222 and a third connecting wall 223. The inner end of the flange body 210 bends forward to form the third connecting wall 223. The front end of the third connecting wall 223 bends towards the center of the window gasket 100 to form the fixing wall 222. The fixing wall 222 is provided with a locking hole 221. The front end of the third connecting wall 223 bends away from the center of the window gasket 100 to form a first mating protrusion 224. The first mating protrusion 224 mates with the first mating groove 1216.

[0065] The first mating protrusion 224, the third connecting wall 213, and the flange body 210 enclose to form a second mating groove 225, which is opposite to the center opening of the window gasket 100. The second mating groove 225 mates with the second mating protrusion 1217.

[0066] In this embodiment of the application, the outer cylinder front flange 200 and the window gasket 100 are connected by the first mating protrusion 224 mating with the first mating groove 1216 and the second mating groove 225 mating with the second mating protrusion 1217, making the fixed connection between the outer cylinder front flange 200 and the window gasket 100 more stable and reliable.

[0067] Combination Figure 1 and Figure 7 A fixing post 226 is provided on the fixing wall 222. The fixing post 226 can be fixedly connected to the window gasket 100, further improving the stability and reliability of the connection between the outer cylinder front flange 200 and the window gasket 100. For example, the fixing post 226 is provided with a fixing hole, and the first connecting wall 121 of the window gasket 100 is provided with a limiting post that cooperates with the fixing hole. Through the cooperation of the limiting post and the fixing hole, the fixing post 226 is fixedly connected to the window gasket 100.

[0068] Optionally, multiple fixing posts 226 may be provided, for example, four fixing posts 226 may be provided; the multiple fixing posts 226 are arranged at intervals along the circumference of the first connecting wall 121, which helps to improve the stability of the connection between the fixing wall 222 and the window gasket 100. Optionally, the multiple fixing posts 226 are evenly spaced along the circumference of the first connecting wall 121 to improve the uniformity of the connection between the window gasket 100 and the outer cylinder front flange 200, and to avoid the window gasket 100 from deforming due to uneven stress.

[0069] Continue to refer to Figure 1 and Figure 7 A gap exists between the shielding part 230 and the window gasket body 110, allowing washing water to easily enter the gap. In this embodiment, the fixed wall 222 is provided with water passage holes 227 to allow water from the gap to enter the outer cylinder. The water passage hole 227 can be an oblong hole as shown in the drawings, or it can be a circular hole, an elliptical hole, etc. To improve water passage efficiency, multiple water passage holes 227 can be provided at intervals along the circumference of the fixed wall 222. This embodiment does not limit the number, shape, or arrangement of the water passage holes 227.

[0070] Combined again Figure 1 and Figure 7 The bottom of the fixed wall 222 of the outer cylinder front flange 200 extends toward the center of the window gasket 100 to form a shielding portion 230. The shielding portion 230 is opposite to at least a portion of the window gasket body 110 of the window gasket 100, serving to shield the window gasket body 110 and prevent the window gasket 100 from directly contacting the load and causing friction. Moreover, the dimension of the shielding portion 230 of the outer cylinder front flange 200 along the vertical centerline H can be consistent with the height of the front flange of existing garment processing equipment. By setting the window gasket body 110, the window gasket 100 retains the pleated portion 111, which is convenient for observation and cleaning.

[0071] Combination Figure 2 as well as Figure 6 The inner end of the top of the first inclined portion 1211 of the window pad 100 extends toward the center of the window pad 100 to form a clothing block 140, which serves to block clothing and prevent clothing from contacting the door and causing abnormal noise.
