Description

Technical Field

[0001] The utility model belongs to the technical field of clothes dryers, and in particular relates to a drum sealing structure of a clothes dryer and a clothes dryer with the drum sealing structure. Background Art

[0002] A clothes dryer is a type of clothing processing device, which is generally used to remove moisture from clothes and other textiles after washing and dehydration. A clothes dryer is usually a drum dryer, and its working principle is to heat the surrounding air, transport it into the drum, and use the hot air to evaporate the moisture in the drum. Most clothes dryers include an inner drum and an outer drum, and the connection between the inner drum and the outer drum is usually provided with a seal. If the seal between the inner drum and the outer drum is poor, the hot air in the inner drum will leak, making the drying effect of the dryer poor. Especially for industrial clothes dryers, the processing precision of the inner drum and the outer drum is not high, which easily leads to poor sealing effect at the connection between the two.

[0003] In the prior art, ordinary felt is usually used to seal between the inner drum and the outer drum of the dryer, which has the following problems: 1) The ordinary felt is fixed on the outer drum, and the ordinary felt and the inner drum have an interference fit, which ensures the sealing effect, but excessive interference will increase the rotational torque of the inner drum; 2) The ordinary felt is fixed on the outer drum, and the interference fit between the ordinary felt and the inner drum is insufficient, which may easily cause poor sealing during the rotation of the inner drum, thereby causing hot air leakage in the inner drum, thereby reducing the drying efficiency; 2) The felt and the inner drum move relative to each other, and the felt will be carbonized due to heat from friction, which will affect the service life of the felt.

The first body 11 has an inclined end surface at one end away from the elastic portion 12, and the inclined end surface is inclined in the direction of the elastic portion 12 in the inward direction. The wear-resistant layer 22 is made of nylon cloth, and the wear-resistant layer 22 is coated on the inner side of the second body 21.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
