[0002] The clothes dryer is a kind of clean household appliance that uses electric heating to evaporate and dry the moisture in washed clothes. It is particularly needed for the difficult drying of clothes in winter in the north and "back to the south" in the south. In addition, the clothes dryer is widely used in industrial production to dry fabrics and improve production efficiency. All clothes dryers are basically provided with an observation window, which is arranged on the front of the clothes dryer. When opened, it can put and take out clothes, and when closed, it can observe the running condition inside the clothes dryer through the observation window.

[0003] According to the search, the Chinese patent document, publication number: CN218291376U, discloses an observation window inner frame structure of a clothes dryer. A connecting device is arranged between the main body of the clothes dryer and the observation window body. The rotating connection between the connecting device and the main body of the clothes dryer allows the connecting device to be rotated before the observation window body is opened, adjusting the opening direction of the observation window body to avoid difficult operation due to insufficient space. A wedge-shaped block is arranged between the connecting device and the main body of the clothes dryer. When the connecting device rotates, the inclined surface of the wedge-shaped block can drive the wedge-shaped block to shrink. The wedge-shaped block moves out of the limiting slot, allowing the connecting device to rotate. Then, the wedge-shaped block is pressed into the adjacent limiting slot under the action of the spring, limiting the connecting device. The connecting device will not rotate when unnecessary. However, during use, the connecting device and the main body of the clothes dryer are connected movably, which can cause serious wear and tear during long-term rotation, reducing the service life. The observation window body and the accommodating cavity are connected by clamping, which makes assembly difficult and is not conducive to disassembly and maintenance, making maintenance time-consuming and troublesome.
