The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The present embodiment provides a drum that may be used in a washing machine or a dryer to accommodate laundry and assist in washing or drying the laundry. As shown in fig. 1 and 2, the drum has a cylindrical structure including a bottom plate 1 and an annular side wall 2. The bottom plate 1 is a circular structure made of metal, and optionally, the bottom plate 1 is made of stainless steel. In order to enhance the structural strength of the base plate 1, a reinforcing rib structure is provided on the base plate 1. The annular side wall 2 is a circular ring-shaped structure made of metal material, and optionally, the annular side wall 2 is made of stainless steel. Two ends of the annular side wall 2 are opened, the bottom plate 1 covers the opening at one end of the annular side wall 2, and the opening at the other end of the annular side wall 2 is a throwing-in opening of clothes. Optionally, the annular side wall 2 is integrally formed with the bottom plate 1 to improve the structural strength of the drum.

The noise reduction and shock absorption sleeve 3 is sleeved on the annular side wall 2, and a hole structure is arranged inside the noise reduction and shock absorption sleeve 3. When the clothes rotate in the drum and metal or plastic parts on the clothes collide with the annular side wall 2, the hole structure can absorb noise and vibration generated by collision, so that the noise and vibration are isolated in the drum, the noise and vibration generated in the working process of the clothes dryer or the washing machine using the drum are reduced, and the use experience of a user using the clothes dryer or the washing machine is improved. Compared with the prior art that noise is isolated only by improving the airtightness of the shell of the clothes dryer or the washing machine, the annular side wall 2 is provided with the noise reduction damping sleeve 3 which is closer to a noise source and a seismic source, so that the noise reduction and damping effects are better.

Because the cylinder need be with the help of the drive belt of cover on it provides power, thereby to avoid the belt direct cover to establish and fall the appearance that the damping sleeve 3 that makes an uproar and lead to skidding phenomenon, as shown in figure 1, be provided with the groove 4 of dodging that is used for dodging the belt on the damping sleeve 3 that makes an uproar falls. The avoiding groove 4 is of an annular strip structure, and the width of the avoiding groove is matched with that of the belt.

In order to form the avoiding groove 4 on the noise reduction and shock absorption sleeve 3, in the present embodiment, as shown in fig. 1 and fig. 2, the noise reduction and shock absorption sleeve 3 includes a first cement sleeve 301 and a second cement sleeve 302, the first cement sleeve 301 is sleeved on one end of the annular side wall 2, the second cement sleeve 302 is sleeved on the other end of the annular side wall 2, and the avoiding groove 4 is formed between the first cement sleeve 301 and the second cement sleeve 302. Optionally, the widths of the first and second mastic sleeves 301 and 302 may be the same or different, and are flexibly selected according to the installation position of the belt.

Further, as shown in fig. 3, in order to prevent the first and second cement sheaths 301 and 302 from slipping off the annular side wall 2 during the rotation of the drum, an anti-slip structure is provided on the outer wall surface of the annular side wall 2. The anti-skidding structure can improve the frictional force between annular lateral wall 2 and first clay cover 301 and second clay cover 302, realizes the inseparable laminating between annular lateral wall 2 and first clay cover 301 and the second clay cover 302.

Optionally, the anti-slip structure comprises a plurality of anti-slip grooves 5, the anti-slip grooves 5 are convenient to manufacture, and the anti-slip effect is good. In the embodiment, as shown in fig. 3, the anti-slip groove 5 is shaped like a kidney, the line of the anti-slip groove 5 is smooth, the appearance is beautiful, and the anti-slip area contacting with the noise reduction and shock absorption sleeve 3 is large. A plurality of anti-skidding grooves 5 rule are arranged, and in order to improve anti-skidding effect, adjacent anti-skidding groove 5 dislocation set in a plurality of anti-skidding grooves 5. Alternatively, a plurality of anti-slip grooves 5 are uniformly arranged around the circumference of the annular side wall 2 and arranged in a corrugated shape as shown in fig. 3. Of course, in other embodiments, the shape and arrangement of the anti-slip grooves 5 can be set according to the requirement.

Alternatively, the anti-slip structure may be provided on the inner wall surface of the noise-reducing damper sleeve 3. Or the inner wall surface of the noise reduction and damping sleeve 3 and the outer wall surface of the annular side wall 2 are simultaneously provided with anti-skidding structures so as to further improve the anti-skidding effect. Further, when the inner wall surface of the noise reduction damping sleeve 3 and the outer wall surface of the annular side wall 2 are both provided with anti-skidding structures, the anti-skidding structures on the inner wall surface and the outer wall surface are preferably set to be the anti-skidding groove 5 and the anti-skidding blocks which are matched, and the anti-skidding blocks can be embedded into the anti-skidding groove 5, so that a better anti-skidding effect is achieved.

Optionally, the first and second mastic sleeves 301, 302 may also be bonded to the annular side wall 2 to improve the strength of the connection between the first and second mastic sleeves 301, 302 and the annular side wall 2. Of course, in other embodiments, the first and second mastic sleeves 301 and 302 may be provided as elastic sleeves made of elastic material, so that the first and second mastic sleeves 301 and 302 can be tightly clamped on the annular sidewall 2. Optionally, the elastic material is an elastic rubber material, and the soft and large-area elastic rubber material can also play a role in better isolating noise.

The embodiment also provides an electric appliance, which comprises the drum, wherein the drum is used for accommodating clothes to be dried. Optionally, the electric appliance can be a clothes dryer or a washing machine, and the clothes to be dried or washed can be accommodated in the drum, so that noise and vibration generated in the clothes drying process of the clothes dryer and the washing process of the washing machine can be reduced to a great extent, the use experience of a user is improved to a great extent, the user is prevented from being polluted by noise, and the clothes dryer and the washing machine are prevented from being damaged due to high-frequency vibration for a long time.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
