Description

FIELD OF THE INVENTION

The present disclosure belongs to the technical field of clothing treatment, and specifically provides a clothing drying apparatus.

BACKGROUND OF THE INVENTION

A clothing drying apparatus is a machine that can dry the clothing, and common clothing drying apparatuses include a clothing dryer, a washing-drying integrated machine, and the like.
In the prior art, taking the clothing dryer as an example, the clothing dryer includes a cabinet, as well as a drying drum and a drying device that are arranged in the cabinet. When the clothing dryer is running, in order that the clothing in the drying drum can be fully dried, the drying drum is driven by a driving member to rotate, and the drying device delivers hot air into the drying drum to dry the clothing in the drying drum.
In the process of drying the clothing, lint on the clothing will flow with the hot air. If the hot air entrained with the lint is directly discharged, the environment will be polluted. Therefore, a filter device is generally provided in the clothing dryer to filter the hot air to prevent the lint from being discharged with the hot air. As the time elapses, more and more lint will be accumulated on the filter device, and the lint needs to be cleaned up regularly. However, since the user cannot accurately judge when a filter member needs to be cleaned, the filter member cannot be cleaned in time, thus affecting smooth circulation of the hot air and further affecting a drying effect of the clothing dryer.
With the advancement of science and technology, an automation level of human life is becoming higher and higher, and machines have gradually replaced manpower to do the daily housework. As a home appliance commonly used in daily life, the clothing drying apparatus has brought great convenience to people's lives. The clothing drying apparatus is classified according to a drying mode, and can be roughly divided into a pulsator clothing dryer and a drum clothing dryer. Taking the drum clothing dryer as an example, in the process of drying the clothing, lint will be generated, and the lint will be adhered to the clothing, which reduces the user experience in use.
In order to solve the above technical problem, a lint collecting groove is provided in a glass window of the drum clothing dryer, and the lint is collected by the lint collecting groove, which prevents the lint from being adhered to the clothing and improves the user experience in use. However, the lint collecting groove of the above drum clothing dryer is fixedly connected or integrally formed with the glass window of the drum clothing dryer, which makes it inconvenient to install and detach the lint collecting groove. When it is necessary to clean up the lint collected in the lint collecting groove, the lint collected in the lint collecting groove can only be pulled out by hand, which greatly affects the user experience in use.
Accordingly, there is a need in the art for a new clothing drying apparatus to solve the above problem.
