The clothes dryer is a common household appliance for drying clothes, the dehydrated clothes are put into a drum of the clothes dryer, dry hot air is input into the drum from an air inlet in the rotation process of the drum, the hot air is in contact with wet clothes to take away moisture, the wet hot air is discharged through an air outlet, and hot air circularly flows to achieve the drying effect on the clothes.

In order to control the operation of the dryer, a humidity sensor is required to be provided in the dryer to detect humidity information of the laundry in the drum. The existing humidity sensor is generally a contact sensor, and the humidity condition of the load is obtained by adopting the direct contact between the clothes and the humidity sensor. In order to make the humidity sensor fully contact with the clothes, the humidity sensor is mostly installed on the filtering bracket, and is generally an electrode type humidity sensor. The bimetal strip of the electrode type humidity sensor is arranged on one side of the filtering support towards clothes, and the other side of the two ends of the bimetal strip extending into the filtering support is connected with the filtering support in a clamping mode.

When the clothes dryer works, the drum drives the clothes in the drum to turn over, so that a small amount of clothes line scraps are generated in the drum, and the line scraps are collected to the back of the filter bracket far away from the clothes through the filter screen of the filter bracket. The accumulation of the thread scraps on the back of the filter screen easily causes the reduction of the creepage distance of two bimetallic strips of the humidity sensor, thereby causing the increase of load and influencing the measurement precision of the humidity sensor; in a serious situation, the bimetallic strip may be short-circuited by the wire scraps, so that the humidity sensor is short-circuited, and the measurement of the humidity sensor fails.
