[0002] The motor of the clothes dryer is installed in combination with the base, which drives the inner drum and the fan to rotate during the drying process, realizing the functions of turning the clothes and cooling the fan. The motor vibrates strongly during operation, so it is necessary to install a vibration-damping washer at the connection between the motor and the base to absorb the vibration during the operation of the motor and reduce the noise generated during the operation of the motor.

[0003] The existing vibration-damping gasket has a relatively simple structure, including an annular resin bracket and a rubber ring formed on the outside of the resin bracket. The vibration-damping gasket is sleeved on the front cover of the motor, and the front cover is fixedly connected to the base through the vibration-damping gasket. However, the connection between the resin bracket and the rubber ring of the existing vibration-damping gasket is not strong enough, and the rubber ring is easy to fall off the resin bracket after long-term use; and the rubber ring is greatly deformed after being squeezed, and the overall structural strength is not ideal. It can be seen that the existing vibration-damping gasket is prone to deformation or damage, which will cause the motor output shaft to swing more, affecting the stability of the fan operation. When the fan runs unstably, it will cause heat accumulation inside the dryer, which will seriously affect the normal use of the dryer.

[0004] In summary, the art needs to improve the vibration-damping gasket used to connect the dryer motor and the base, so as to increase its structural strength, reduce the probability of deformation or damage, and ensure the normal and stable operation of the dryer. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 and Figure 2As shown, the first preferred embodiment of a vibration-damping gasket of the present application is shown, wherein the vibration-damping gasket comprises an annular bracket 1 and a rubber ring 2 wrapped around the outside of the bracket 1, and the outside of the bracket 1 has a circle of connecting parts 10 embedded in the rubber ring 2. By providing the connecting part 10, the connection stability between the rubber ring 2 and the bracket 1 can be strengthened, and the rubber ring 2 and the bracket 1 can be prevented from being separated after long-term use, which affects the normal operation of the motor and has a longer service life. After the connecting part 10 is embedded in the rubber ring 2, a supporting inner core is formed, which improves the structural strength of the rubber ring 2 and reduces the deformation of the rubber ring 2 when it is squeezed. After the motor is installed, the deformation of the vibration-damping gasket is reduced, which helps to reduce the swing of the motor output shaft, ensure the stability of the fan operation, and reduce the noise.

[0029] Specifically, the rubber ring 2 has a thread 21 on its exterior, and one side of the rubber ring 2 is a chamfered end 20 that is screwed into the base of the clothes dryer.

[0030] In this embodiment, the connecting portion 10 has an inclined section 11 and a supporting section 12. The inner side of the inclined section 11 is connected to the outer wall of the bracket 1, and the outer side of the inclined section 11 is connected to the supporting section 12, and the supporting section 12 does not contact the bracket 1; wherein the supporting section 12 extends from the outer side of the inclined section 11 in a direction away from the chamfered end 20. When the vibration damping washer is installed, the rubber ring 2 is squeezed, and due to its asymmetric structure, the side of the supporting section 12 away from the inclined section 11 is squeezed and moves relatively downward, driving the supporting section 12 and the inclined section 11 to bulge outward at the joint, squeezing the corresponding position of the rubber ring 2 from the inside, thereby improving the connection stability between the rubber ring 2 and the bracket 1, and at the same time improving the overall structural strength. Preferably, the supporting section 12 is coaxial with the bracket 1.

[0031] like Figure 3 As shown, it is a second preferred embodiment of a vibration-damping washer of the present application. In this embodiment, the connecting portion 10A has an inclined section 11A and a supporting section 12A.

When installing the vibration-damping washer described in this embodiment, the side of the supporting section 12A away from the inclined section 11A is squeezed at the beginning of screwing in, and the installation is relatively more labor-intensive, but the disassembly and replacement is more labor-saving. Preferably, the supporting section 12A is coaxial with the bracket 1.

[0032] like Figure 4 As shown, it is a third preferred embodiment of a vibration-damping gasket of the present application. In this embodiment, the connecting portion 10B is a convex strip with a trapezoidal cross-section. Preferably, the connecting portion 10B is located in the middle of the side of the bracket 1. The connecting portion 10B has a simple structure and is easier to manufacture.

In this embodiment, the connecting portion 10C is a convex strip with a T-shaped cross section, including a protrusion 11C and a support portion 12C. One end of the protrusion 11C is connected to the outer side surface of the bracket 1 and extends in a direction away from the outer side surface of the bracket 1. The end of the protrusion 11C away from the outer side surface of the bracket 1 is connected to the support portion 12C, and the support portion 12C extends to both sides along the protrusion 11C. In this embodiment, the connecting portion 10C supports the rubber ring 2 more evenly. Preferably, the protrusion 11C is located in the middle of the side of the bracket 1, and the support portion 12C is coaxial with the bracket 1.

[0034] See also Figure 6 and Figure 7 The present application also provides a motor 5 using the vibration-damping washer, wherein the motor 5 has a front cover 4 connected to the base of the clothes dryer, the output shaft of the motor 5 passes through the front cover 4, the vibration-damping washer is arranged around the end of the front cover 4, and the end of the vibration-damping washer away from the front cover 4 is coaxial with the limit clamp 3, and the front cover 4 is connected to the base of the clothes dryer through the vibration-damping washer. The motor using the vibration-damping washer runs more stably and has less noise.
