[0035] The conductive structure 140 is disposed on the inner side of the door body 130 and is electrically connected to the controller.
[0036] In the technical solution of the embodiment of the present application, when the clothes are processed, the inner drum 120 rotates in the shell 110, and the inner drum 120-clothing-conductive structure 140-controller forms an electrical circuit; as the humidity of the clothes changes, the resistance value of the inner drum 120-clothing-conductive structure 140 will change, so the controller will obtain the moisture content of the clothes based on this; by using the inner drum 120 as a detection electrode for humidity measurement, it is simple and there is no situation where the electrical circuit cannot be formed due to the dirt of the inner drum 120; and the conductive structure 140 is arranged on the inside of the door body 130 as another detection electrode for humidity measurement. When the clothes processing device 10 is not in use, the door body 130 can be opened to clean the conductive structure 140, and there is no situation where the electrical circuit cannot be formed due to dirt; therefore, the technical solution of the present application does not have the situation where the moisture content of the clothes cannot be measured due to the dirt of the drum.
[0037] It should be noted that the inner drum 120 of the clothing processing device 10 is a component made of metal material, for example, the inner drum 120 is a stainless steel inner drum 120, which itself has a conductive function; in the technical solution of the embodiment of the present application, the inner drum 120 is used to place clothes while also having the function of humidity detection, which can reduce the components used for humidity measurement, which is conducive to saving costs and internal space.

In an embodiment, the conductive structure 140 may be a metal conductive sheet, such as a copper sheet, a copper alloy sheet, or a conductive graphene sheet.
[0039] As an optional embodiment of the above embodiment, the laundry processing device 10 further includes a first lead (not shown), and the conductive structure 140 is connected to the controller via the first lead. In the embodiment, the first lead is used to form an electrical circuit. One end of the first lead is connected to the conductive structure 140, and the other end is connected to the controller. One end of the first lead can be soldered or electrically connected to the conductive structure 140 via a terminal, and the other end can be soldered or connected to the controller via a terminal.
[0040] As an optional implementation of the above embodiment, Figure 4 As shown, the door body 130 is connected to the housing 110 via a hinge mechanism 160, and the first lead wire is passed through the hinge mechanism 160. In an embodiment, the first lead wire is hidden within the door body 130 and then passed through the hinge mechanism 160 into the housing 110 to connect to the controller.
