[0002] In the prior art, the sealing way between the door body of the clothes drying machine and the drum of the clothes drying machine is to install a hollow sealing strip in the installation groove of the front support of the clothes drying machine. When the door body of the clothes drying machine is closed, the inner frame plane of the door body extrudes the hollow sealing strip, and the contact surface of the hollow sealing strip is always in close contact to form a seal. Since the hollow sealing strip is filled with air, in the process of closing the door, as the closing angle gradually decreases, the hollow sealing strip is extruded and deformed more and more, and the air in the hollow sealing strip is extruded out. When the door body is closed to the final position, the hollow sealing strip is extruded to the maximum deformation, and the closing angle at this time is called 0 degree angle.

[0003] However, when the clothes drying machine is closed, especially when the door lock that can be pushed to pop open the door is used, the door body closing angle is required to exceed 0 degree angle when the door is closed, so as to overcome the spring force inside the door lock and make the door lock bolt reach the rotation angle of locking the door. Then the user removes the closing force, and the door body is pushed back to 0 degree angle under the action of the door lock spring force. Since the periphery of the sealing strip cannot be fixed on the washing machine, the periphery of the sealing strip will turn inward when the door is closed, which will affect the sealing performance of the sealing strip and cause the problem of poor sealing of the door body.

[0004] Therefore, the present application is proposed. SUMMARY

The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0043] In the description of the present application, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are merely for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0044] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] As Figures 1 to 6As shown, the door sealing ring 1 of the clothes dryer according to the present application comprises a ring-shaped body 11, an auxiliary mounting portion 12 and a plug-in portion 13. The plug-in portion 13 is arranged along the circumferential direction of the rear end surface of the ring-shaped body 11 and extends rearward from the rear end surface of the ring-shaped body 11. The auxiliary mounting portion 12 is located at the outer periphery of the plug-in portion 13 and is arranged along the circumferential direction of the rear end surface of the ring-shaped body 11 and extends rearward from the rear end surface of the ring-shaped body 11.

[0046] The sealing ring 1 according to the present application can be mounted on the inner side of the door body or the front support 2 by arranging the auxiliary mounting portion 12 and the plug-in portion 13 on the rear end surface of the ring-shaped body 11. The auxiliary mounting portion 12 is located at the outer periphery of the plug-in portion 13 and serves as an auxiliary fixing portion of the sealing ring 1. The auxiliary mounting portion 12 can prevent the sealing ring 1 of the door body of the clothes dryer from being pressed when the door is closed, which can cause the outer peripheral portion of the sealing ring 1 to turn inward toward the clothes-throwing opening and result in poor sealing of the sealing ring 1. The sealing ring 1 does not shift when it is pressed when the door is closed, thereby improving the sealing performance of the door body of the clothes dryer.

[0047] The auxiliary mounting portion 12 extends rearward from the rear end surface of the ring-shaped body 11 in a direction parallel to the direction in which the plug-in portion 13 extends rearward from the rear end surface of the ring-shaped body 11. The auxiliary mounting portion 12 and the plug-in portion 13 are respectively arranged to extend rearward from the rear end surface of the ring-shaped body 11 along the axial direction of the ring-shaped body 11.

[0048] Preferably, the ring-shaped body 11 has a solid structure or a hollow cavity in the interior thereof, and the door body can press the ring-shaped body 11 to seal the door body.

[0049] As shown in the drawings, Figures 1 to 3 As shown, the front end and the rear end of the door sealing ring 1 are as shown in the drawings. The plug-in portion 13 has a ring-shaped structure, the auxiliary mounting portion 12 has a ring-shaped structure, and an annular groove 18 is formed between the plug-in portion 13 and the auxiliary mounting portion 12. The outer peripheral wall of the plug-in portion 13, the rear wall of the ring-shaped body 11 and the inner peripheral wall of the auxiliary mounting portion 12 form the annular groove 18.

[0050] In a preferred embodiment, the plug-in portion 13 is arranged close to the inner peripheral wall of the ring-shaped body 11, and the auxiliary mounting portion 12 is arranged close to the outer peripheral wall of the ring-shaped body 11. The inner diameter of the plug-in portion 13 is the same as the inner diameter of the ring-shaped body 11, and the outer diameter of the auxiliary mounting portion 12 is the same as the outer diameter of the ring-shaped body 11.

[0051] As shown in the drawings, Figure 3As shown, the plug-in part 13 is provided with an undercut 16 which is formed by the inner and outer peripheral walls of the plug-in part 13 extending forwardly and obliquely. The undercut 16 can prevent the plug-in part 13 from loosening after installation and enhance the stability of the plug-in part 13.

[0052] Preferably, the auxiliary installation part 12 can also be provided with an undercut 16.

[0053] The outer peripheral wall of the annular body 11 near the front end is provided with a protruding part 17. Preferably, the protruding part 17 is an annular protruding part 17.

[0054] The sealing ring 1 further comprises a lip 14 which extends from the front end of the annular body 11 to the inside of the annular body 11. Preferably, the annular body 11 is of solid structure. The lip 14 can be pressed against the inner side of the door body to play a sealing role.

[0055] Preferably, the lip 14 extends from the front end of the annular body 11 to the inside of the annular body 11 or extends from the inner peripheral wall of the annular body 11 near the front end of the annular body 11 to the inside of the annular body 11.

[0056] The sealing ring 1 further comprises a protection part 15 which is protrudingly arranged on the inner peripheral wall of the annular body 11. The front end surface of the protection part 15 is connected with the lip 14 to protect the root of the lip 14. The inner diameter of the protection part 15 is greater than the inner diameter of the plug-in part 13.

[0057] The protection part 15 is an annular sealing body which is arranged on the inner peripheral wall of the annular body 11. The protection part 15 is protrudingly arranged on the inner peripheral wall of the annular body 11 and the front end thereof is connected with the root of the lip 14 to protect the lip 14. The protection part 15 protrudes inwardly from the plug-in part 13.

[0058] The connection between the inner peripheral wall of the protection part 15 and the rear side wall of the lip 14 is provided with a transition groove (not shown in the figure) which is recessed inwardly of the sealing ring 1. The included angle between the extension line of the groove bottom of the transition groove toward the groove opening and the extension direction of the lip 14 is an acute angle α1. Preferably, the included angle α2 between the extension line of the groove bottom of the transition groove toward the groove opening and the axis of the protection part 15 is the same as the acute angle α1. The cross section of the transition groove is U-shaped or symmetrically arc-shaped.

[0059] When the inner side of the door body presses the lip 14, the transition groove can facilitate the bending of the lip 14 toward the rear end.

[0060] The lip 14 is inclined from the front end of the annular body 11 toward the rear end of the annular body 11.

[0061] The sealing ring 1 is an integral structure, which facilitates the assembly of the sealing ring on the dryer and improves the sealing performance of the door.

[0062] like Figures 4 to 6 As shown, the present invention also provides a dryer, which has any of the door sealing rings 1 described above. The dryer is a dryer or a washer-dryer combo, and the dryer in the washer-dryer body can be located at the upper or lower part of the washer-dryer body.

[0063] Specifically, such as Figures 5 to 6 As shown, the dryer also includes a door and a front support 2. The door is used to close the clothes loading port of the dryer.

[0064] The front support 2 is used to support the front end of the clothes dryer. The front support 2 has a first opening 21, which is arranged opposite to the clothes loading port.

[0065] The door sealing ring 1 is installed on the front support 2 and is located between the front support 2 and the door.

[0066] The auxiliary mounting part 12 and the plug-in part 13 of the sealing ring 1 are mounted on the front support 2. The auxiliary mounting part 12 and the plug-in part 13 cooperate with each other to prevent the door from squeezing the sealing ring 1 when the dryer is closed, causing the outer circumference of the sealing ring 1 to flip inward, resulting in the door sealing ring 1 shifting and the dryer door sealing performance being poor. This improves the door sealing performance of the dryer.

[0067] The dryer also includes a front panel 3, which is located in front of the front support 2 and has a second opening 31, which is opposite to the first opening 21. The inner diameter of the second opening 31 is larger than the inner diameter of the first opening 21.

[0068] The front support 2 protrudes from the front end face of the second opening 31 and has an insertion groove 215. The insertion part 13 of the sealing ring 1 is installed in the insertion groove 215. The auxiliary mounting part 12 is located between the front support 2 and the second opening 31 of the front plate 3.

[0069] The insertion part 13 of the sealing ring 1 of the present invention is installed in the insertion groove 215 of the front support 2. The auxiliary installation part 12 of the sealing ring 1 is located between the front support 2 and the second opening 31 of the front plate 3. This can prevent the outer peripheral part of the sealing ring 1 from flipping into the clothes inlet when the door is closed and squeezed, causing the sealing ring 1 to fall off or shift from the washing machine. At the same time, the door sealing ring 1 can also cover the exposed front end of the clothes inlet of the washing machine, which can prevent the end face of the plastic front support from abrading the clothes when taking out and putting in clothes.

[0070] The lip 14 is at least partially suspended in the first opening 21, and the lip 14 is located between the front end face of the front support 2 and the inner side of the door body. The lip 14 of the present invention may not have a hollow structure, and the sealing ring 1 may not have a hollow structure.

[0071] like Figure 6 As shown, the first opening 21 of the front support 2 includes a first segment 211, a second segment 212, and a third segment 213 that are bent and extended sequentially from the rear end of the front support 2 toward the front end of the front support 2. The first segment 211 and the third segment 213 extend from the rear side to the front side. The inner diameter of the first segment 211 is larger than the inner diameter of the third segment 213. The second segment 212 is connected between the first segment 211 and the third segment 213.

[0072] Preferably, the first opening 21 is a variable diameter opening. The inner diameter of the first segment 211 gradually decreases from the rear to the front. The second segment 212 extends radially inward along the second opening 31, and the inner diameter of the third segment 213 remains unchanged, serving as a through hole.

[0073] A rib 214 extends from the outer wall of the third segment 213 toward the front end, and the insertion groove 215 is formed between the rib 214 and the third segment 213. The auxiliary mounting part 12 is located on the outer peripheral wall side of the rib 214.

[0074] The axial extension length of the rib 214 is equal to the axial extension length of the third segment 213.

[0075] The plug portion 13 is matched with the plug groove 215, and the plug groove 215 is an annular plug groove 215.

[0076] When installing the door sealing ring 1, the plug part 13 is inserted into the plug groove 215 of the front support 2. The buckle 16 on the plug part 13 can be deformed to prevent the plug part 13 from coming loose from the plug groove 215.

[0077] The door is mounted on the second opening 31 of the front panel 3. A matching decorative panel 5 is provided on the front end face of the front panel 3, and the decorative panel 5 is disposed on the outer periphery of the second opening 31 of the front panel 3. The inner diameter of the opening of the decorative panel 5 is greater than or equal to the inner diameter of the second opening 31. The protrusion 17 of the sealing ring 1 matches the inner diameter of the decorative panel 5 and is located within the inner diameter of the decorative panel 5, which can improve the integrity and aesthetics of the front end of the dryer.

[0078] Further, the second opening 31 is formed extending from the front plate 3 to the rear side, the inner diameter of the second opening 31 is greater than the outer diameter of the convex rib 214, and the auxiliary mounting portion 12 is located between the outer peripheral wall of the convex rib 214 and the inner peripheral wall of the second opening 31.

[0079] The annular groove 18 between the auxiliary mounting portion 12 and the plug-in portion 13 of the sealing ring 1 is sleeved on the convex rib 214. The auxiliary mounting portion 12 matches with the inner peripheral wall of the second opening 31 and the outer peripheral wall of the convex rib 214.

[0080] The application installs the plug-in portion 13 of the sealing ring 1 in the plug-in groove 215 and installs the auxiliary mounting portion 12 around the plug-in portion 13 between the convex rib 214 around the plug-in groove 215 and the second opening 31 of the front plate 3, which can assist in fixing the peripheral part of the sealing ring 1, prevent the door body from extruding the sealing ring 1 and causing the peripheral part of the sealing ring 1 to turn inward, improve the installation stability of the sealing ring 1, improve the door body sealing performance of the clothes dryer, and improve the drying efficiency of the clothes dryer.

[0081] Preferably, the auxiliary mounting portion 12 is plugged between the outer peripheral wall of the convex rib 214 and the inner peripheral wall of the second opening 31.

[0082] Preferably, the second opening 31 is arranged extending from the front plate 3 to the rear side and then extending to the rear side along the axial direction.

[0083] The application extends the lip 14 of the sealing ring 1 to the inside of the first opening 21 and suspends in the first opening 21 of the front support 2. When the door of the clothes dryer is closed, the observation window glass 4 on the inside of the door body presses the lip 14 to seal the door body. The lip 14 has no hollow structure inside and does not need to extrude the air in the sealing ring 1. The user saves labor when closing the door, which ensures the sealing performance of the door body and improves the user experience.

[0084] Specifically, the observation window glass 4 is a bowl-shaped structure protruding inward, and the opening of the bowl is provided with a flange 41 extending outward. The flange 41 abuts on the front end of the sealing ring 1. The edge of the flange 41 matches and abuts on the arc surface on the front end surface of the sealing ring 1.

[0085] The inclination angle of the lip 14 matches the inclination angle of the flange 41, and the flange 41 presses the lip 14 when the door is closed.

[0086] During the process of closing the door, especially when using a push-bolt type door lock, the door body does not need to extrude the hollow sealing ring 1 to exhaust air, but only needs to overcome the spring force in the door lock. The user only needs to use a small force when closing the door, which improves the user's experience of closing the door.

[0087] The front support 2 is provided with a plug groove 215, and the plug portions 13 of the sealing ring 1 are respectively clamped in the plug groove 215. By arranging the auxiliary mounting portion 12 on the outer periphery of the plug portion 13, the auxiliary mounting portion 12 can be arranged in front of the front support 2 and the second opening 31 of the front plate 3, thereby playing an auxiliary fixing role. The auxiliary mounting portion 12 can prevent the inner side of the door body from extruding the lip 14 when the door is closed, so that the outer periphery of the sealing ring 1 is turned inward, thereby causing displacement of the sealing ring 1 and poor sealing.

[0088] The clothes dryer adopting the sealing ring 1 can adopt a push-pull type door lock, and has the advantages of small opening force, good user experience, and good appearance of the machine body after the door is opened.

[0089] The front end of the protection portion 15 is connected with the root of the lip 14, and the rear end of the protection portion 15 abuts on the front end face of the third opening segment 213 of the front support 2. By arranging the protection portion 15, the deformation of the lip 14 when the door is closed can be avoided, and the lip 14 contacts the front end face of the front support 2, so that the wear of the lip 14 can be avoided.

[0090] When the observation window glass 4 extrudes the lip 14 backward, the arrangement of the transition groove can reduce the resistance when the lip 14 is turned over, thereby facilitating the closing of the door body.

[0091] The above description is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as the above preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and equivalent embodiments with equivalent changes are equivalent.
