The utility model relates to clothes treatment equipment technical field discloses a sterilization component, backplate subassembly and clothes treatment equipment, this sterilization component includes the casing, and the casing forms the cavity, and the casing is provided with the air inlet portion and the air outlet portion with the cavity intercommunication on the casing, and the inner side wall of casing is coated with photocatalyst layer,
light source,
light source sets up in the cavity of casing, and the
light energy of
light source provides excitation photocatalyst layer and carries out
photocatalytic reaction, generates sterilization material, wherein, the air inlet portion is used for the
airflow to enter the cavity, and the
airflow that enters the cavity carries the sterilization material and flows from the air outlet portion. Through
coating photocatalyst layer on the inner side wall of the casing with the cavity, and setting up the light source corresponding with the photocatalyst layer in the cavity of casing, make the
airflow that enters the cavity can mix with the active substance with the sterilization effect, and promote the active substance with the sterilization effect to
discharge from the air outlet with the airflow, to enter the clothes treatment cylinder and carry out the sterilization to the clothes to be handled.
