[0002] A dehumidifier is a household appliance used to reduce indoor air humidity. It absorbs moisture from the air, converts moisture into water and collects it, thereby creating a more comfortable and dry living or working environment for people. Dehumidifiers are mainly used to prevent mold growth, bacterial reproduction, furniture deformation, electronic equipment moisture and other humidity-related health and property problems caused by high humidity. Controlling the spatial scope of dehumidification is to ensure the targeted and energy-efficient dehumidification effect, avoid energy waste caused by excessive dehumidification, and meet the specific needs of spaces of different sizes to achieve the best indoor humidity balance. Existing dehumidifiers rarely have a functional structure that controls the dehumidification space range, making it difficult to meet the personalized usage needs of users.
